Preparation, characterization, and desalination study of polystyrene membrane integrated with zeolite using the electrospinning method

The novel composite membranes of Styrofoam (polystyrene) integrated with natural zeolite particles were produced using the electrospinning method for desalination purposes. The product was then characterized using FTIR, XRD, and TGA. Subsequently, the effect of different zeolite concentrations, namely 0, 5, 10, 15, 20, and 30 wt.% on its morphological structure and effectiveness was determined. Desalination of artificial seawater was carried out using the gravitational filtration principle to confirm the membrane's capabilities, after which its performance was evaluated using 4 wt.% NaCl solution. The morphological analysis showed that the composite membrane obtained has a smooth surface with microdomains on a few parts, which indicates the presence of zeolite. The result showed that the product integrated with 30 wt.% zeolites had the best performance in the desalination of artificial seawater. This was determined by comparing the conductivity value of the seawater before and after the process. The conductivity led to an 82.63% decrease using 30 wt.% zeolites. The developed polystyrene membrane embedded with zeolite has good thermal stability, hence, it can be used for desalination.

Effect of zeolite contents on mineral evolution and heavy metal solidification in alkali-activated MSWI fly ash specimens

Municipal solid waste incineration fly ash (MSWIFA) with a high heavy metal concentration must be consolidated before disposal in a landfill. Alkali-activated technique contributes significantly to boosting the degree of heavy metal solidification and usage ratio on MSWIFA material. In this work, zeolite, a new additional siliceous material, was employed to improve the properties of a pure alkali-activated MSWIFA (FZ0) matrix. When compared to other FZ specimens with varying zeolite concentrations (0–50 wt%), the compressive strength of alkali-activated MSWIFA with 40 wt% zeolite substitution (FZ40) after 3, 7, 14 d curing was the highest. The compressive strength of partial FZ specimens reduced somewhat after 28 d of curing due to dry shrinkage. According to magic angle spinning nuclear magnetic resonance (MAS NMR) data, the predominant amorphous products in FZ specimens were C-(A)-S-H. Based on X-ray diffraction (XRD) data, new minerals (tobermorite, tilleyite, and calcite) were discovered and quantified in the FZ matrix. Fourier transform infrared spectroscopy (FT-IR) findings revealed partial Na2SO4 in FZ0 specimens. Notably, the leaching concentrations of Pb, Zn, Cu, Cr, Ni, and Cd in FZ0 and other FZ specimens that met Chinese criteria were significantly lower than in the original MSWIFA. Meanwhile, additional FZ specimens showed superior solidification tendencies on Pb, Zn, Cr, and Cd than FZ0 specimens. The inclusion of zeolite may increase the solidification efficiency of heavy metals in the MSWIFA matrix and has a promising application.

A fly ash-derived polybenzoxazine/zeolite A bilayer coating with excellent superhydrophobicity and corrosion resistance

Organic resin-based coating is the most effective and cost-efficient method for preventing metal corrosion, but it is always plagued by its hydrophilicity, brittleness and preparation-induced pore flaws. In this study, a double-layer superhydrophobic anti-corrosion coating with concentration gradient variation was designed and prepared, using benzoxazine as the matrix and waste fly ash-prepared zeolite A as the inorganic filler. The upper layer of the designed coating with the low concentration of zeolite formed a superhydrophobic surface with a water contact angle of 158.8° ± 0.9°, while the high concentration of zeolite in the lower layer improved the adhesion of the coating to the metal substrate with a surface hardness of 5H and an adhesion of 5B, which were both significantly improved in comparison to the pure benzoxazine coating. In particular, the impedance value of our designed coating is 2.677 × 108 Ω, which is 4 orders of magnitude greater than the pure benzoxazine coating. The benzoxazine/zeolite A (from fly ash) bilayer coatings developed mechanical properties, anti-fouling and corrosion resistance, which not only boosted the use of fly ash but also created a new type of anti-corrosion coating.

Hydrophobic ZSM-5/styrene-butadiene-styrene (SBS) membrane for the removal of pyridine from aqueous solutions via pervaporation

New mixed matrix membranes (MMMs) of poly(styrene-butadiene-styrene) (SBS) incorporated with hydrophobic ZSM-5 zeolite (calcinated and non-calcinated) were prepared and characterized by various analyses. The performance of fabricated membranes was investigated in a pervaporation (PV) experimental setup for removing pyridine from aqueous solutions and the results indicated a notable increase in total flux. The influence of feed temperature (25–55ºC) on the pure SBS membrane performance was studied and the results were compared. It was found that an increase in feed temperature increased the permeation flux and decreased the separation factor. Incorporating ZSM-5 into the membrane matrix substantially influenced the separation performance of the fabricated membranes. The sample with 20 wt% calcinated zeolite (C.ZSM-5) represented the highest separation factor. C.ZSM-5 loading up to 20 wt% reduced total flux while it was increased with further increments in zeolite content. The highest separation factor and pervaporation separation index (PSI) for 20 wt% C.ZSM-5 sample at 45ºC feed temperature obtained at about 72 and 80,223 (g/m2h), respectively.

Study of Thermal Behavior of Epoxy Composites Filled with Different Natural Zeolites

One of the ways to enhance thermal stability and reduce the flammability of polymers is the introduction of fillers with flame retardant properties. The paper studies the effect of natural zeolites of the Sakhaptinsk and Shivyrtuysk deposits on the thermal stability and flame retardancy of epoxy composites. The thermal stability of epoxy composites was characterized by thermogravimetric analysis in oxidizing (air) and inert (argon) atmospheres. The parameters of thermo-oxidative degradation and thermal degradation of the samples with a filler concentration of 0, 1, 5, and 10 wt% were studied. Flame retardancy of epoxy composites filled with zeolite was evaluated using the limiting oxygen index. The limiting oxygen index increases with increasing concentration of natural zeolites in the epoxy matrix. The study revealed some differences in the first and second stages of heating the epoxy composites depending on zeolite type and did not reveal significant difference in the thermal behavior of the epoxy composites in the third stage of the heating. Thermal stability and flame retardant properties are more dependent on the zeolite content in the epoxy matrix than zeolite type.

Performance of Equilibrium Zeolite in Water-Based Mud at Elevated Temperature Conditions

This study looks at the performance of nano equilibrium zeolite treated drilling fluids at high temperatures conditions, and their potential as alternatives for oil-based muds (OBM). Mud samples for this study were prepared and aged with the equilibrium zeolite nanoparticles concentrations of 0.0 g, 0.5 g, 1.0 g and 1.5 g. Tests were performed to determine the rheological, filtration control properties, the pH and consequently the thermal stability of the study mud samples over a temperature range of 120 °F to 360 °F. One sample without the equilibrium zeolite served as a control for the study. From the results obtained, all the nano samples had their rheological properties not exhibiting much significant variation with temperature, thus they were more thermally stable, with the optimum nanoparticle concentration being 1.5 g. It was also hypothesized that the nano equilibrium zeolite behaved as thinners, since they were able to reduce the shear stresses, yield points, plastic viscosities and gel strengths of the mud samples as temperature was varied incrementally. It was therefore concluded that the optimum concentration of aged equilibrium zeolite has the potential to act as a thermal stability additive for Water Based Mud systems (WBMs).

A Comparison Study for The Performance of Polyethersulfone Ultrafiltration Mixed Matrix Membranes in The Removal of Heavy Metal Ions from Aqueous Solutions

Polyethersulfone (PES) ultrafiltration membrane blending NaX zeolite crystals as a hydrophilic additive was examined for zinc (II) and lead ions Pb (II) removal from aqueous solutions. The effect of NaX zeolite content on the permeation flux and removal efficiency was studied. The results showed that adding zeolite to the polymer matrix enhanced the permeation flux. The permeation flux of all the zeolite/PES matrix membranes was higher than the pristine membrane. No significant improvement was observed in the removal of Zn (II) ions using all prepared membranes as the removal percentage did not raise above 29.2%. However, the removal percentage of Pb (II) ions was enhanced to 97% using a membrane containing 0.9%wt. zeolite. Also, it was found that this membrane has a higher ion exchange capacity than the other prepared membranes. Two isotherm models (Langmuir model, and Freundlich model) were employed in the analysis of the ion exchange equilibrium data. The experimental data best fitted the Langmuir model with R2 of 0.889 than the Freundlich model.

Use of Natural Zeolite and Glass Powder Mixture as Partial Replacement of Portland Cement: The Effect on Hydration, Properties and Porosity.

The study investigates effect of the additive consisting of natural zeolite (clinoptilolite) and soda lime glass powder on the hydration, mechanical properties and porosity of Portland cement concrete. The effect of mineral additive on the technological, physical-mechanical properties and porosity of the mortar was investigated by increasing the content of natural zeolite and glass powder added to the mortar up to 20% by weight of cement in increments of 5% and different particles size of natural zeolite. The mixes with the best technological and mechanical properties were identified and further studies were conducted by replacing 10% and 15% of cement with natural zeolite and soda lime glass with an average grain size of 59.3 μm, 29.0 μm or 3.6 μm of zeolite, and 29.6 μm of glass powder. The hydration process and microstructure of hardened cement paste modified with the aforementioned mineral additives was analysed by microcalorimetry, X-ray diffraction tests and thermogravimetric analysis. The optimal composition of cement paste and particle size distribution of natural zeolite were determined to achieve the higher flexural and compressive strength and lower open porosity. The mixture of mineral additives has the highest effect in terms of flexural and compressive strength and open porosity when added at the proportion 75:15:10 (cement:natural zeolite:soda lime glass) and when zeolite with an average particle size of about 3.6 μm is used

Influence of the Zeolite ZSM-22 Precursor on a UF-PES Selective Substrate Layer for Salts Rejection.

Fabrication of the ZSM-22/Polyethersulfone (ZSM-22/PES) membranes as selective salt filters represent a growing membrane technological area in separation with the potential of high economic reward based on its low energy requirements. The incorporation of ZSM-22 zeolite material as additives into the PES polymer matrix has the prospective advantage of combining both the zeolite and polymer features while overcoming the limitations associated with both materials. This work investigated the influence of the nature of the silica precursor on ZSM-22 zeolite hydrothermally synthesised using colloidal (C60) and fumed (C60) silica to Si/Al of 60. The successful synthesis of the highly crystalline zeolitic materials was confirmed through XRD, FTIR, and SEM with EDX. The ZSM-22 additives were directly dispersed into a PES polymeric matrix to form a casting solution for the preparation of the ZSM-22/PES selective substrate layers via a phase inversion method for salts rejection. The polymeric PES was selected as an organic network in which the content of the ZSM-22 zeolite (ranging between 0 and 1.0 wt.%), was obtained and characterised by XRD, FTIR, and SEM analysis, as well as water contact angle (WCA) measurement and dead-end filtration cell. The phase inversion preparation method has induced the resulting ZSM-22/PES NF substrates anisotropy, as attributed to a high water flux to the above 700 L·m−2·h−1; high selectivity and rejection of salts to above 80% is revealed by the obtained results. The materials also exhibited improved antifouling behavior to above 70% flux recovery ratios. As such, the nature of the silica precursor influences ZSM-22 zeolite synthesis as a potential additive in the PES polymer matrix and led to the enhanced performance of the pure PES ultrafiltration membrane.

A polyurethane foam membrane filled with double cross-linked chitosan/carboxymethyl cellulose gel and decorated with ZSM-5 nano zeolite: Simultaneous dye removal

A novel bio-based polyurethane foam was fabricated using double cross-linked chitosan/carboxymethyl cellulose gel, filled with ZSM-5 nano zeolite, and hot-pressed into the membrane. The prepared foam membrane was characterized using FESEM, FTIR, BET, TGA, and pHZPC analyses and then used for continuous dye removal. The results modification of polyurethane foam with chitosan/carboxymethyl cellulose gel and ZSM-5 nano zeolite would increase the retention ability of positive cationic methylene blue. Also, the foam could simultaneously remove methyl orange, eriochrome black T, and methylene blue from the binary and trinary solutions but could effectively be used to selectively removal methylene blue. In addition, the dye removal ability at the breakthrough was enhanced with decreasing flow rate, and increasing bed height, pH, initial dye concentration, and nano zeolite content in the foam. To describe the breakthrough curves different models were utilized which best fits were obtained with Modified Dose-Response as compared to Thomas, Adams & Bohart, Yoon–Nelson, and Wolborska models.

The effectiveness of use of natural zeolites in feeding of young pigs

In order to reduce the number of the main components of compound feed, to realize the genetic potential of the productivity of young pigs, to increase their productivity and to balance feeding diets, it is necessary to use various feed and mineral additives, including natural origin. Such additives include silicon-containing zeolite. The purpose of the research was to establish the optimal dose of silicon-containing zeolite in the recipes of compound feed for young pigs and to identify its effect on the dynamics of live weight and feed expenditures for its production. For the experiment has been carried out three recipes of compound feed with a content of 3, 4, 5 % of the silicon-containing zeolite additive from the mass of the compound feed were developed. In the experiment young pigs of the 1st control group have been received farm compound feed, without the content of silicon-containing zeolite. Animals of the 2nd experimental group have been received experimental compound feed with 3 % of silicon-containing zeolite from the mass of compound feed. Young pigs of the 3rd experimental group have been consumed compound feed with 4 % of silicon-containing zeolite from the mass of compound feed during the experiment. Animals of the 4th experimental group have also been consumed experimental compound feed with 5 % of silicon-containing zeolite from the mass of compound feed. Silicon-containing zeolite was included in the compound feed, replacing grain feed. It was found according to the results of the experiment that the best dose of inclusion of this additive was 3 % of the mass of compound feed. At the same time, it was found that the gain in live weight of pigs in the 2nd experimental group increased by 13,6 %, in the 3rd group by 7,2 %, and in the 4th experimental group decreased by 4,4 %, compared with the 1st control group. Studies have shown that the addition of silicon-containing zeolite to the compound feed fof pigs of the 2nd and 3rd experimental groups did not affect the consumption of compound feed, and in the 4th experimental group there was a decrease in the consumption of compound feed. The feed consumption for the live weight gain of pigs in the 2nd, 3rd and 4th experimental groups decreased by 12,1 %, 6,7 and 0,2 % during the experiment period, compared with the 1st control group.

Effects of natural zeolite and sulfate environment on mechanical properties and permeability of cement–bentonite cutoff wall

Cement–bentonite (CB) slurry cutoff walls are extensively utilized to restrict the horizontal flow of fluids. In this study, cement was replaced by four various contents of 0%, 10%, 20%, and 30% by natural zeolite to evaluate its effects on the unconfined compressive strength, flexural strength, tensile strength, and the coefficient of permeability of cement–bentonite–zeolite (CBZ) specimens. Since underground cutoff walls are always in danger of sulfate attack, the CBZ specimens were immersed in three different containers with three different pH values of 2, 5, and 8 to study the sulfate resistance of this material. Results have indicated that the strength of specimens decreases with an increase in zeolite content at early ages; however, increasing the amount of zeolite up to 20% improves the mechanical properties and permeability of cutoff wall materials at late ages. The bentonite/cement (B/C) ratio equal to 0.2 shows a relatively better response than B/C ratios equal to 0.14 and 0.3. Curing specimens in the sulfate environment increased the mechanical strength of specimens and decreased the coefficient of permeability at first ages. At the late ages, curing in sulfate solutions manifested disadvantageous effects on specimens; however, specimens containing zeolite indicated higher sulfate resistance than specimens without zeolite.

Moisture content and application rates of inert dust: effects on dust and wheat physical properties

Grain protectants such as inert dust help prevent quality deterioration during post-harvest storage. Understanding the physical characteristics of inert dust and inert dust treated wheat kernels could help develop solutions to flow problems of stored grain. This research investigated the effects of the moisture content of a synthetic amorphous zeolite and the rates of application on some physical properties of the amorphous zeolite and wheat kernels. Three levels of moisture (2.0%, 6.0%, and 10.0%) of the zeolite were applied at three rates (0.5 g/kg, 1.0 g/kg, and 2.0 g/kg) on 100 g wheat samples (10% m.c, wet basis) in triplicates. Image analysis, laser diffraction, Thermogravimetric analysis (TGA), Scanning Electron Microscopy (SEM), gas pycnometry, and the Single-Kernel Characterization System (SKCS) were used to characterize the physical properties. The particle size of the amorphous dust increased with increasing moisture content. Conversely, shape parameters (circularity, aspect ratio, convexity, and solidity) generally decreased with increasing dust moisture contents. When wheat was mixed with the amorphous dust at increasing rates and moisture levels, the bulk density of wheat decreased, while the tapped density and the angle of repose increased, resulting in higher Hausner ratios and Carr Index values. Treating wheat with the amorphous dust at the highest moisture (35%) and application rate (2.0 g/kg) caused the treated wheat to transition from an acceptable flowability to a poor flowability along with a decrease in wheat kernel hardness. Our data suggest, however, that a range of moisture content (2-6%) and an application rate (0.5 g/kg) mitigate the adverse effects on wheat flowability. This study also highlights the importance of drying any amorphous dust or allowing dust to equilibrate to the experiment temperature before conducting tests on physical properties.

A New Mixture Criterion for the Improvement of the Compressive Strength of Adobe Using Zeolite as Stabilizer

The use of zeolite as a stabilizer for adobe has proven to have the ability to improve its physical and chemical properties. This is shown in the positive results in terms of strength gain and water absorption resistance in adobe blocks. In this work, an investigation was carried out to evaluate the use of zeolite as adobe stabilizer. The adobes were made with two different types of soil with different content of zeolite (5, 10, 15, 20% by weight) maintaining the zeolite-lime ratio 1:1. The samples were tested on compressive strength and water absorption. The deterioration of the adobes was analyzed under conditions of extreme humidity. The results of this study revealed that adobe behavior is influenced by the synergistic relationship between soil, zeolite and lime, showing significant changes in compressive strength even under extreme humidity conditions. It was also observed that the chemical composition of the soil influenced the development of the pozzolanic reaction. The stabilization of adobes with 15% of zeolite showed the best mechanical behavior, before and after deterioration assay. Hence, zeolite promises to be a good alternative as a stabilizer in adobe construction systems.

Thermal Properties of Illite-Zeolite Mixtures up to 1100 °C.

Illitic clays are the commonly used material in building ceramics. Zeolites are microporous, hydrated crystalline aluminosilicates, they are widely used due to their structure and absorption properties. In this study, illitic clay (Füzérradvány, Hungary) was mixed with natural zeolite (Nižný Hrabovec, Slovakia) with up to 50 wt.% of zeolite content. The samples were submitted to thermal analyses, such as differential thermal analysis, differential scanning calorimetry, thermogravimetry, and dilatometry. In addition, the evolution of thermal diffusivity, thermal conductivity, and specific heat capacity in the heating stage of firing were measured and discussed. The amount of the physically bound water in the samples increased along with the amount of zeolite. The temperature of the illite dehydroxylation (peak temperature) was slightly shifted to lower temperatures, from 609 °C to 575 °C (for sample IZ50). On the other hand, the mass loss and the shrinkage of the samples significantly increased with the zeolite content in the samples. Sample IZ50 reached 10.8% shrinkage, while the sample prepared only from the illitic clay contracted by 5.8%. Nevertheless, the temperature of the beginning of the sintering (taken from the dilatometric curves) decreased from 1021 °C (for illitic clay) to 1005 °C (for IZ50). The thermal diffusivity and thermal conductivity values decreased as the amount of zeolite increased in the samples, thus showing promising thermal insulating properties.

Evaluation of the Adsorptive Potential of Zeolite Volcanic Tuff in Single and Binary Aqueous Solutions of the Basic Blue 41 Cationic Dye

AbstractA volcanic tuff of clinoptilolite type has been assessed in regards to its efficiency on Basic Blue 41 (BB‐41) cationic dye removal from aqueous solutions. Optimal working conditions were established by considering influences of the particle sizes, initial pH, dye concentration, contact time, and temperature. Tuff samples have been characterized by using SEM/EDX, FT‐IR, and N2 gas adsorption‐desorption techniques. Experimental data at equilibrium showed a better fitting of adsorption kinetics on pseudo‐second‐order and Langmuir models, whereas the thermodynamic parameters indicate an endothermic spontaneous process. Tuff particles of 47 μm medium sizes, which own the highest zeolite content, were found to be the most suitable for practical use as adsorbents, attaining a maximum adsorptive capacity of 123.5 mg g−1 pure dye at 323 K, equivalent to 303 mg g−1 commercial product containing 40 % dye. A potential interference involving the retention pattern was furthermore evaluated within binary systems with other two cationic dyes, Rhodamine B (RhB) and Methylene Blue (MB). The adsorbent shows a relevant selectivity towards BB‐41, influenced by commercial dye additives, structural configuration, molecular size, and contact time, with the 99.7 % dye removal efficiency at 24 hours only slightly depressed in binary systems with RhB ‐ 97.4 %, respective MB ‐ 90.2 %. This study confirmed the tuff particles as efficient adsorbents for the treatment of textile wastewater effluents.

The effect of zeolite incorporation on the physical properties of silver-reinforced glass ionomer cement

Zeolite can impart antibacterial properties to dental materials in the long-term when incorporated with inorganic cations. However, due to its porosity, it may jeopardize the mechanical integrity of the dental material. The aim of this project was to determine the effect on physical properties when zeolite is added to commercially available Ag-reinforced Glass Ionomer Cement (GIC). Sample groups were prepared according to the percentage of zeolite-clinoptilolite (0% - control, 0.5%, 1%, 2%, and 4% wt) added to Ag-GIC. Water sorption, solubility, Vickers hardness, and flexural strength were determined. Specifically, 10 × 2 mm circular disks were fabricated for the Vickers hardness, water sorption, and water solubility tests and 25 × 5 × 2 mm bars were created for the flexural strength test. The results from the surface hardness, water sorption, and flexural strength tests suggested that adding 0.5–4% wt of zeolite to Ag-reinforced GIC did not diminish its physical properties. However, the water solubility results showed that higher concentrations (2–4% wt) of zeolite had a statistically significant increase in water solubility compared to the control. Up to 4% wt zeolite can be incorporated into Ag-reinforced GIC without compromising mechanical properties. Incorporation of 0.5–1% wt zeolite to Ag-reinforced GIC will maintain an adequate surface hardness, water sorption, and flexural strength without compromising water solubility. Further research is needed to determine the effects of higher water solubility on clinical efficacy of zeolite modified Ag-GIC.Graphical abstract

The Effects of Incorporating Ag-Zn Zeolite on the Surface Roughness and Hardness of Heat and Cold Cure Acrylic Resins

One of the most widely used materials for the fabrication of prosthetic dental parts is acrylic resin. Its reasonable mechanical and physical properties make it a popular material for a wide range of dental applications. Recently, many attempts have been made to improve the mechanical and biological properties of this material, such as by adding fibres, nanoparticles, and nanotubes. The current study aimed to evaluate the effects of adding an antimicrobial agent, Ag-Zn zeolite, on the surface roughness and hardness of the denture base resins. Ag-Zn zeolite particles were chemically prepared and added at different concentrations (0.50 wt.% and 0.75 wt.%) to the heat cure (HC) and cold cure (CC) acrylic resins. Zeolite particles were characterized and confirmed using X-ray diffraction (XRD) and Energy-Dispersive X-ray Spectroscopy (EDX) attached with a Scanning Electron Microscope (SEM). Sixty disk shape specimens (40 mm diameter and 2 mm thickness) were fabricated from the HC and CC resins with and without the zeolite. All the specimens were divided into two main groups based on the acrylic resins, then each was subdivided into three groups (n = 10) according to the concentration of the Ag-Zn zeolite. A surface roughness and a hardness tester were used to measure the surface finish and hardness of the specimens. The analysed data showed that the surface roughness values significantly decreased when 0.50 wt.% and 0.75 wt.% zeolite were incorporated in the HC resin specimens compared to the control group. However, this reduction was not significant in the case of CC resin, while the surface hardness was significantly improved after incorporating 0.50 wt.% and 0.75 wt.% zeolite for both the CC and HC resins. Incorporating Ag-Zn zeolite with acrylic resin materials could be beneficial for improving their surface finish and resistance to surface damage as defined by the higher hardness.

Exploring the Adsorption Properties of Zeolite in a New Skin Care Formulation

Introduction: Zeolites are natural or synthetic aluminosilicates, characterized by a regular and microporous crystalline structure that plays a particularly active role in neutralizing free radicals, screening UV rays and in the adsorption of toxins and heavy metals. Skin is one of the main areas for the accumulation of toxic substances released by environmental pollutants. The biological scavenger activity of zeolite opens a wide spectrum of applications in cosmetics and dermatology. Up to now, there is little evidence related to the use of natural zeolite in cosmetics. Aim: The purpose of this work was to evaluate the ability of zeolite to retain heavy metals in a new skin care formulation, in order to provide a proof of principle of its employment in the field of cosmetics. Materials and Methods: Taking the advantages of spiked samples, we studied the in vitro adsorption properties of zeolite in a new skin care formulation. The removal capacities of Cadmium, Lead, Chromium, Nickel and Cobalt were studied, using the inductively coupled plasma optical emission spectrometry (ICP-OES). First of all, the better concentration of zeolite was defined, testing two different proportions of zeolite, from 1% to 3%, keeping all other components constant. Then, on the 3% formulation, the adsorption properties of each single metal were measured. Results and Conclusions: Our preliminary study demonstrated the selectivity of zeolite in retaining Cadmium (p < 0.0001), Nickel (p = 0.026), in a 3% zeolite-based formulation. This work provides a proof of principle of zeolite employment in the field of cosmetics. Based on the data collected, our work provides a scientific proof of principle of zeolite employment in the field of cosmetics. New and extensive research will be needed to explore all the potential benefits of zeolite.
