Adsorption Of Zinc Ions Research Articles

Zinc ions adsorption under dynamic conditions with the use of Georgian minerals

The article deals with the studies of chemically active natural minerals of Georgia: travertine and limestone under dynamic conditions, which have been explored for the first time as adsorbents in the process of aqueous solutions’ purification from zinc ions. Tests have been conducted in filtration columns at different hydraulic loads until the ratio of zinc concentration in sewage waters Ck to initial zinc concentration Co (Ck/Co) reached the value of 0,95. The dependence of zinc adsorption degree on aqueous solution delivery rate, time duration of adsorbent operation and dependence of zinc ions adsorption rate constant on contact time have been studied. Zinc adsorption percentage, with initial solution delivery at the rate of 0,3 l/h, was equal to 82% and 70% for limestone and travertine, respectively. The best outcome during column tests has been reached in case of limestone, for which the zinc adsorption percentage comprised 80% with contact time duration equal to 5 hours.

Preparation of graphene oxide-supported hydrogel adsorbent for Zn ions removal

A composite hydrogel was prepared using in situ polymerisation of acrylic acid and acrylamide monomers. The prepared hydrogel was improved by addition of graphene oxide nanosheets in the range of 0.1–0.3 wt%. These modified samples were then employed for the adsorption of zinc ions. The batch adsorption experiments were carried out at ambient conditions and pH = 7.0. The adsorbents’ morphological features, structural characteristics and mechanical behaviours were assessed using techniques such as Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction and dynamic mechanical thermal analysis. Incorporating graphene oxide into pure hydrogels markedly enhances their mechanical robustness and swelling behaviour. When graphene oxide is added at levels up to 0.2 wt%, there is a notable elevation in the glass-transition temperature and the mechanical modulus of the hydrogels. In contrast, further addition of graphene oxide decreases the mechanical properties due to nanoparticle agglomeration. The water diffusion and the swelling mechanism follow pseudo-Fickian and Schott kinetic models, respectively. The adsorption kinetics followed a pseudo-second-order model, reaching equilibrium within 75 min. The data from the adsorption isotherm conformed well to the Langmuir model.

Organic micro/nanospheres assembled from a [2 + 2] Schiff base macrocycle for efficient adsorption of zinc ions and dyes

A Schiff base macrocycle (M) containing both isophthalamide and bissalicylaldehyde scaffolds was successfully designed and synthesized. M exhibited typical aggregation-induced enhanced emission characteristics in a mixed solvent of DMF/water, and showed high selectivity for the recognition of Zn(II) over other metal ions. The binding process, binding ratio, and association constant of M with Zn(II) were estimated through UV–vis and fluorescence spectra titrations, isothermal titration calorimetry, and 1H NMR titration experiments, and the detection limit towards Zn(II) was calculated as 1.03 × 10−7 mol·L−1. Interestingly, a large amount of micro/nanospheres of M with remarkable size uniformity were obtained from the reaction medium with sulfuric acid as a catalyst. On the basis of exploring the formation process of the micro/nanospheres and the key factors affecting their morphology and size, the Zn(II) and dye adsorption experiments were carried out. The results indicated that the micro/nanospheres of M can be applied to Zn(II) and dye adsorption with satisfactory removal rates.

Manipulating the d-band center of bimetallic molybdenum vanadate for high performance aqueous zinc-ion battery

Vanadium-based oxides have good application prospects in aqueous zinc ion batteries (AZIBs) due to their structures suitable for zinc ion extraction and intercalation. However, their poor conductivity limits their further development. The d-band center plays a key role in promoting adsorption of ions, which promotes the development of electrode materials. Here, a series of MoV2O8 compounds with oxygen defect (Od-MoV2O8) were synthesized by a simple hydrothermal process and a subsequent vacuum calcination process through strict control of the deoxidation time. Theoretical calculations reveal that the abundant oxygen vacancies in MoV2O8 effectively regulate the d-band center of the zinc ion adsorption site. This precise control of the d-band center enhances the zinc ion adsorption energy of MoV2O8, lowers the migration energy barrier for zinc ions, and ultimately significantly boosts zinc storage performance. The specific capacity is as high as 282.4 mAh/g after 100 cycles at 0.1 A/g, and it also shows excellent performance and outstanding cycle life. In addition, the maximum energy density of Od-MVO-0.5 (MoV2O8 sample deoxidized for 0.5 h) is 343.3 Wh kg−1. Importantly, the mechanism of Zn2+ storage in Od-MoV2O8 was revealed by the combination of in situ and ex situ characterization techniques.

Three-dimensional N,P co-doped graphene hydrogel cathode for zinc-ion hybrid capacitor with high specific capacitance and excellent rate performance

Zinc-ion hybrid capacitor (ZHSC) is recognized as a favorable energy storage device due to the combined advantages of battery-type anode and capacitor-type cathode. However, it still remains a huge challenge to achieve a high-specific-capacitance cathode without compromising the rate capability for high-performance ZHSC. Here, a three-dimensional hierarchical nitrogen and phosphorus co-doped reduced graphene oxide hydrogel (NPGH) is synthesized with small-sized graphene oxide precursors via one-step hydrothermal reduction and in-situ doping, which is firstly used as cathode for ZHSC without adding extra conductive additives and binders. In this case, small-sized graphene sheets can increase and shorten ions diffusion channels for the efficient utilization of active surface compared with commonly-used large-sized counterparts. Moreover, nitrogen and phosphorus co-doping can synergistically enhance the conductivity, provide additional active sites, and promote the adsorption of zinc ions, which is well demonstrated by electrochemical analysis, ex situ characterization and DFT theoretical calculation. Attributed to the synergy, NPGH-based ZHSC displays large specific capacitance (251.3 F g−1, 0.5 A g−1), outstanding rate performance (79 %, 50 A g−1) and excellent cycle stability. This work proposes a novel strategy of tailoring rGO cathode by simultaneous size effect and doping engineering, which shows a great promise of constructing high-performance rGO based ZHSC.

Binding between Cu2+/Zn2+ and aged polyethylene and polyethylene terephthalate microplastics in swine wastewaters: Adsorption behavior, and mechanism insights

Microplastics (MPs) have aroused growing environmental concerns due to their biotoxicity and vital roles in accelerating the spread of toxic elements. Illuminating the interactions between MPs and heavy metals (HMs) is crucial for understanding the transport and fate of HM-loaded MPs in specific environmentally relevant scenarios. Herein, the adsorption of copper (Cu2+) and zinc (Zn2+) ions over polyethylene (PE) and polyethylene terephthalate (PET) particulates before and after heat persulfate oxidation (HPO) treatment was comprehensively evaluated in simulated and real swine wastewaters. The effects of intrinsic properties (i.e., degree of weathering, size, type) of MPs and environmental factors (i.e., pH, ionic strength, and co-occurring species) on adsorption were investigated thoroughly. It was observed that HPO treatment expedites the fragmentation of pristine MPs, and renders MPs with a variety of oxygen-rich functional groups, which are likely to act as new active sites for binding both HMs. The adsorption of both HMs is pH- and ionic strength-dependent at a pH of 4–6. Co-occurring species such as humic acid (HA) and tetracycline (TC) appear to enhance the affinity of both aged MPs for Cu2+ and Zn2+ ions via bridging complexation. However, co-occurring nutrient species (e.g., phosphate and ammonia) demonstrate different impacts on the adsorption, improving uptake of Cu2+ by precipitation while lowering affinity for Zn2+ owing to the formation of soluble zinc-ammonia complex. Spectroscopic analysis indicates that the dominant adsorption mechanism mainly involves electrostatic interactions and surface complexation. These findings provided fundamental insights into the interactions between aged MPs and HMs in swine wastewaters and might be extended to other nutrient-rich wastewaters.

Artificial aluminum-doped SiO2 aerogel coating layer regulating zinc ions flow for highly reversible dendrite-free zinc anodes

As a sustainable, safe, and cost-effective alternative to conventional lithium-ion batteries, aqueous rechargeable zinc-metal-based batteries have attracted significant attention in large-scale energy storage. However, their practical application is hindered by zinc anode degradation, primarily dendrite growth and corrosion, which compromise battery performance and lifespan. Herein, we present an aluminum-doped silica (Al-SiO2) aerogel coating layer to address these issues. The aluminum-doped silica aerogel coating layer offers improved hydrophilicity and zinc ion adsorption capabilities because of its porous structure, high surface area, and functional groups. By facilitating uniform zinc ion deposition and providing a physical barrier against corrosion, the Al-SiO2 aerogel coating layer significantly mitigates dendrite formation and extends the electrochemical stability and operational lifespan of aqueous rechargeable zinc-metal-based batteries. Symmetric cell tests reveal that zinc anodes coated with Al-SiO2 can achieve stable cycling over 3000 h, indicating exceptional reversibility and rate performance, much better than that of the bare Zn anode. Furthermore, the Al-SiO2 aerogel-coated zinc anode coupled with MnO2 cathode forms a stable rechargeable full battery. This work contributes to the body of knowledge on advanced materials for energy storage, highlighting the potential of aerogel coatings as a scalable and effective solution for improving the performance and durability of zinc metal anode for aqueous rechargeable zinc-metal-based batteries.

Highly efficient recovery of Zn (II) from zinc-containing wastewater by tourmaline tailings geopolymers to in-situ construct nanoscale ZnS for the photodegradation of tetracycline hydrochloride

While treating zinc-containing wastewater, recovering zinc for reuse as a secondary resource has significant environmental and economic benefits. Herein, based on the alkali-activated tourmaline tailings geopolymers (TTG) after adsorption of zinc ions (Zn (II)), a series of new composites with in-situ construction ZnS nanoparticles on TTG (ZnS/TTG) were synthesized, and used as photocatalysts for the photodegradation of tetracycline hydrochloride (TCH) in solution. Specifically, ZnS nanoparticles were uniformly and stably distributed in the layered structure of TTG, interweaving with each other to generate an interfacial electric field, which could induce more photocarrier generation. Meanwhile, TTG acted as an electron acceptor to accelerate the electron transfer at the interface, thus enhancing the photodegradation activity for TCH. The active radical quenching experiments combined with the ESR indicated that the active species produced during the photocatalytic degradation of TCH by ZnS/TTG composites were •O2− and photogenerated h+. When the initial concentration of Zn (II) was 60 mg/L, the synthesized 60-ZnS/TTG composites (0.5 g/L) reached 91.53% degradation efficiency of TCH (10 mg/L) at pH = 6. Furthermore, the possible pathways and mechanism of 60-ZnS/TTG composites photodegraded TCH were revealed with the aid of degraded intermediates. This report not only proposed valuable references for reusing heavy metal ions and removing TCH from wastewater, but also provided promising ideas for realizing the conversion of used adsorbents into high-efficiency photocatalysts.

Mathematical Evaluation of Direct and Inverse Problem Applied in Breakthrough Models of Metal Adsorption

The treatment of industrial effluents has great environmental and human health importance. The purification of water from polluting components, such as metals and organic compounds, can be considered one of the main applications in this field, with adsorption being one of the main treatment methods. Therefore, with the objective of describing the dynamics of the process in an adsorption column and estimating the parameters involved, in this work, an algorithm for the Method of Lines (MOL) was used in order to numerically solve the model formed by the mass balance in liquid phase, the linear driving force equation (LDF), and the Langmuir isotherm for equilibrium. In addition, a sensitivity analysis of the phenomenon was carried out in relation to the parameters and a subsequent estimation of these was made through the Monte Carlo technique via the Markov chain (MCMC). The validation algorithm was created using data from actual breakthrough curves found in the literature. The experimental data were obtained from the literature for the adsorption of Cadmium (Cd), Copper (Cu), Nickel (Ni), Zinc (Zn), and Chrome (Cr) ions. Among all the estimates, the one that had the lowest adjustment to the data was that related to zinc metal, which had an R2 equal to 0.8984. For the other metals, the correlation coefficient had a value closer to unity. This demonstrates that, in general, the estimates were good enough to represent the dynamics of adsorption.

Enhanced heavy metal adsorption capacity of surface-functionalized Philippine natural zeolite in simulated wastewater

The adsorption efficiency of surface-functionalized Philippine natural zeolite (PNZ) for heavy metal uptake from single and mixed metal ion-simulated wastewater solution is reported in this work. Atomic adsorption spectroscopy (AAS) findings revealed that NaCl-modified PNZ (MPNZ) exhibited the highest zinc ion adsorption of 99.96 % while PNZ yielded an adsorption of 95.61 %. The adsorption isotherms of raw PNZ and MPNZ both show similar shapes that reflect Type IV adsorption-desorption isotherms with Type H2 hysteresis loop which can be observed for micro-mesoporous materials (pore containing 2–50 nm). An increase in PNZ pore size from 10.11 nm to 13.36 nm for NaCl-PNZ and 15.59 for NaOH-PNZ is observed after alkaline treatment. EDS confirmed the decrease in Si/Al ratio from 4.02 to 3.76, indicative of possible higher negative charge in the PNZ framework which is favorable for an enhanced Coulombic or electrostatic interaction with the cationic heavy metals being detected in this study. MPNZ demonstrated an adsorption capacity of 99.96 % for copper in mixed-ion solution while 88.49 % and 86.67 % were obtained for zinc and nickel, respectively. These values are higher compared to PNZ having only 32.21 % uptake for zinc and 38.00 % for nickel. A hierarchy of the average metal adsorption capacity showed the order: copper > nickel > zinc. Rapid adsorption at the first hour of the adsorption reaction was attained in all solutions while samples with pH 9 exhibited the highest Ni2+ and Zn2+ percent removal. Moreover, the increase in initial solution concentration led to lower adsorption efficiency and the maximum uptake was attained at 100 ppm. The equilibrium data of adsorption and mechanism were suitably described by Langmuir isotherm model. With these, surface functionalization of PNZ has further enhanced its cationic adsorption capacity on heavy metals in both single and mixed-ion solution having promising potential for wastewater remediation.

Adsorption of Zinc(II) Ion by Spent and Raw Agaricus bisporus in Aqueous Solution

A significant environmental concern globally is the pollution of water bodies as a result of heavy metals. To date, various attempts have been made to effectively remove heavy metals, such as those that use synthetic and biogenic materials to abate and control water pollution. The biological removal of pollutants from water is an efficient and environmentally friendly technique. In this study, we evaluated the biosorption characteristics of Zn2+ ions from aqueous solution by spent composed of raw Agaricus biosporium (RAB) and A. biosporium (SCAB). We added different biosorption doses, metal ions, and initial concentrations of pollutants to explore the adsorption of Zn2+ by RAB and SCAB. We applied pseudo-first- and second-order models to investigate the biosorption kinetics. According to our results, the rate of Zn2+ removal from the aqueous solution using raw biomass was significantly lower than that using sodium citrate-treated biomass of SCAB. When the Zn2+ concentration increased from 10 mg L−1 to 200 mg L−1, the rate of removal of RAB decreased from 73.9% to 38.4%, and that of Zn2+ by SCAB decreased from 99.9% to 75.9%. As we increased the biosorbent dose, the rate of Zn2+ removal by SCAB increased. Interestingly, Zn2 biosorption was inhibited by heavy co ions (Cu2+ and Pb2+) and light metals (e.g., Na+, Mg2+, K+, and Ca2+). When treating wastewater polluted with Zn2+, Pb2+, and Cu2+, SCAB showed good potential. The results of this study provide a scientific basis for an environmentally sound approach to controlling water pollution.

The highly beneficial requirements for zinc ion adsorption are 10 ppm as preliminary concentration, 0.21 g as pomegranate and banana rinds dosage and 5.5, 5.23 as pH for banana and Pomegranate rind. Elimination results follow the Langmuir replica with qmax of 25.64 mg/g for banana and 41.66 mg/g for Pomegranate rind. The elimination process kinetic was equipped well via second -order equivalence. It was examined that the zinc ion adsorption procedure on both bio sorbents is instinctive procedure, endothermal for banana and pomegranate rind. A distinctive enhancement in the adsorptive shell was observed once the adsorption procedure that revealed through scanning electron microscope.

Competitive adsorption of copper and zinc ions by Tetradesmus obliquus under autotrophic and mixotrophic cultivation

The competitive adsorption mechanism of Tetradesmus obliquus on copper and zinc ions was explored under varied cultivation conditions. Removal efficiency of Tetradesmus obliquus for these ions was evaluated during autotrophic and mixotrophic cultivation. The results revealed that Tetradesmus obliquus demonstrated achieved removal efficiencies of 74.30 %, 86.48 %, 84.55 %, and 65.33 % for 16 mg/L of Zn2+, Cu2+, and a mixture of Cu2+ and Zn2+, respectively, under autotrophic conditions. Conversely, under mixotrophic conditions, Tetradesmus obliquus demonstrated improved removal efficiencies of 86.90 %, 92.31 %, 92.30 %, and 71.94 % for Zn2+, Cu2+, and a Cu-Zn mixture, along with adsorption capacities of 38.57 mg/g, 43.86 mg/g, 23.15 mg/g, and 15.24 mg/g, respectively. This represents an increase of 46.65 %, 31.16 %, 29.47 %, and 43.50 % compared to the autotrophic group, respectively. The second-order kinetic equation and Langmuir isotherm model, as proposed, successfully fitted the experimental data for kinetics and isotherms of Zn2+ and Cu2+ in the monometallic system. The maximum adsorption capacities were determined to be 43.22 mg/g and 69.41 mg/g, respectively, under mixotrophic cultivation conditions. The Extended Langmuir isotherm model best fit all experimental data in the mixed system. The presence of Cu2+ markedly reduced Zn2+ adsorption, whereas the presence of Zn2+ had no effect on Cu2+ adsorption. The 3D fluorescence results further confirmed that glucose addition stimulates algal cells to produce additional extracellular polymers, consequently enhancing metal adsorption by microalgae. These research findings confirm that culturing Tetradesmus obliquus in a mixed environment enhances heavy metal removal during water treatment, which is of significant importance for environmental remediation and sustainable water purification.

Nitrogen-Vacancy-Rich VN Clusters Embedded in Carbon Matrix for High-Performance Zinc Ion Batteries.

Vanadium nitride (VN) is a potential cathode material with high capacity and high energy density for aqueous zinc batteries (AZIBs). However, the slow kinetics resulting from the strong electrostatic interaction of the electrode materials with zinc ions is a major challenge for fast storage. Here, VN clusters with nitrogen-vacancy embedded in carbon (C) (Nv -VN/C-SS-2) are prepared for the first time to improve the slow reaction kinetics. The nitrogen vacancies can effectively accelerate the reaction kinetics, reduce the electrochemical polarization, and improve the performance. The density functional theory (DFT) calculations also prove that the rapid adsorption and desorption of zinc ions on Nv -VN/C-SS-2 can release more electrons to the delocalized electron cloud of the material, thus adding more active sites. The Nv -VN/C-SS-2 exhibits a specific capacity and outstanding cycle life. Meanwhile, the quasi-solid-state battery exhibits a high capacity of 186.5mAhg-1 , ultra-high energy density of 278.9Whkg-1 , and a high power density of 2375.1Wkg-1 at 2.5Ag-1 , showing excellent electrochemical performance. This work provides a meaningful reference value for improving the comprehensive electrochemical performance of VN through interface engineering.

Study of the adsorption of copper, nickel and zinc ions on a zeolite-containing sorbent synthesized from thermal power plant waste

The study investigated the possibility of using ash and slag waste from thermal power plants as an alternative raw material source to obtain an inexpensive zeolite-containing sorbent, which was synthesized by hydrothermal synthesis by adding 20% sodium hydroxide at a temperature of 120оC for 24 hours. Using X-ray diffraction, it was established that the synthesized material mainly consists of the framework aluminosilicate mineral hydrosodalite. Using the obtained material, the sorption of copper, zinc, and nickel cations from aqueous media was studied using the Langmuir, Freundlich, and Dubinin-Radushkevich models. The constants of these equations were determined, the values of the isobaric-isothermal potential and the free energy of ion adsorption were calculated. It has been established that the sorption of metal ions is of a physical nature. It was found that the Dubinin–Radushkevich equation better describes the process of adsorption of zinc and nickel, and the Langmuir equation better describes the sorption of copper ions. The decrease in the degree of affinity of sorbed ions to the surface of the synthesized zeolite-containing sorbent was determined as follows: . Thus, based on the obtained values of sorption of copper, zinc, and nickel ions, the fundamental possibility of using ash and slag waste as a raw material source for obtaining inexpensive and effective zeolite-containing sorbents for extracting the above metal ions from aqueous media was established.

Adsorption of Zinc and Iron Ions from Aqueous Solution Using Waste Material as Adsorbent

Reducing or eliminating ions of toxic heavy elements such as iron and zinc from aqueous solutions has been adopted in this research. The batch process is used to remove metal ions using a cheap adsorbent material that is called hawthorn nucleus. In addition, the influences of contact time, pH, metal ions concentration, and adsorbent dose on the removal percentage have been studied. This study showed that adsorption or removal efficiency increases over time and the quantity of the adsorbent material, as well as pH showed that the equivalent and negative charges category is preferred for adsorption by the hawthorn nucleus. The highest removal efficiency was found to be 91% for zinc and 95% for iron. In such conditions, i.e., 120 minutes time, the metal concentration is 25 ppm, the amount of the adsorbent material is 5 g/L and pH is 10 for zinc and 7 for iron. Adsorption isotherm and kinetics were also investigated for both metal ions. The results showed that the adsorption findings followed Langmuir isotherm and the pseudo-second-order kinetic for adsorption isotherm and kinetics, respectively.

Electronically modified hierarchical porous carbon by N, P heteroatoms for zinc ion hybrid capacitor

Due to the low cost and steady physicochemical properties of carbon materials, zinc-ion hybrid capacitors (ZICs) composed of carbon cathode and Zn anode have aroused considerable attracts in recent years. However, the unsatisfactory capacity and electrochemical kinetics of carbonaceous cathode hinder its application in ZICs. Herein, a facile self-template thermal treatment method was proposed to prepare N, P co-doped hierarchical porous carbons (NP-HPCs). The electronically modified NP-HPC3 has an ultrahigh ratio of active N species and abundant micropores, which is favorable for zinc ions adsorption. In addition, the three-dimensional cross-linked network with abundant mesoporous cavities synchronously boosts electrons/ions transfer kinetics. Ex-situ characterization shows that the introduction of N, P heteroatoms is helpful to improve the adsorption of zinc ions. Thanks to these favorable structural characteristics, the NP-HPC3 displays an exceptional specific capacitance (275.0 F g−1 at 0.1 A g−1) and rate capability (182.0 F g−1 at 20 A g−1). More significantly, the NP-HPC3-based ZIC delivers a prominent energy density of 107.8 Wh kg−1 at a power density of 90.7 W kg−1, a long cycle life (96.9 % capacitance retention after 10,000 cycles) together with an outstanding anti-self-discharge performance (0.001145 V h−1@200 h). This study not only affords a feasible and environmental route to construct advanced heteroatom doped carbonaceous materials, but also explores the interrelation between zinc ions storage behavior and structural characteristics of carbon materials.

Adsorption of Chromium, Copper, Lead, Selenium, and Zinc ions into ecofriendly synthesized magnetic iron nanoparticles.

The iron nanoparticles (Fe-NPs) have been synthesized using an environmentally friendly and simple green synthesis method. This study aims to obtain an aqueous extract from natural material wastes for synthesizing Fe-NPs. The produced Fe-NPs were evaluated as adsorbents for removing Pb, Se, Cu, Zn, and Cr from aqueous solutions. The formation of Fe-NPs was observed on exposure of the aqueous extract to the ferrous chloride and ferric chloride solutions. The characterization of the synthesized Fe-NPs was carried out using different instrumental techniques. As a function of the initial metal ion concentration, contact time, and various doses, the removal of the heavy metal ions was investigated. The UV-Vis spectrum of Fe-NPs showed a peak at 386 nm, 386 nm, 400 nm, 420 nm, 210 nm, 215 nm, and 272 nm of banana, pomegranate, opuntia, orange, potato, and onion, respectively. The FT-IR spectra confirmed the attachment of bioactive molecules from plants on the Fe-NPs surface. The effective reduction of metal ions was greatly aided by the -OH functional groups. The functional groups were examined and responsible for adsorption process by nanoparticle powder sample, these peaks are 3400 cm-1, 2900 cm-1, 1600 cm-1,1000 cm-1, and 1550 cm-1. The magnetization measurements revealed superparamagnetic behavior in the produced iron oxide nanoparticles. Heavy metal ions uptake followed a time, dose, and initial concentration-dependent profile, with maximum removal efficiency at 45 min, 0.4 g, and 3.0 mg/L of metal concentration, respectively.
