Microwave-assisted magnetic biochar for removal of hexavalent chromium from aqueous solution

ABSTRACT In this study, biochars were prepared by pyrolysis of tea waste and rice husk and hexavalent chromium (Cr(VI) sorption was obtained after post-modification of biochars with magnetic iron nano/micro-particles. The maximum sorption of Cr(VI) by magnetic tea waste biochar (MTWB) was 99.9% followed by 97.36% for magnetic rice husk biochar (MTRHB) at pH 5.2. Among studied competing ions, sulfate ions (SO4 2-) considerably reduced the sorption of Cr(VI) up to ~66.5% for both biochars. The surface functional groups such as – OH, C-H, Fe-O and porous biochars structure loaded with iron nanoparticles helped in Cr(VI) adsorption by ion exchange and electrostatic interactions as indicated by FTIR, XPS and SEM-EDS data. Both Cr(III) and Cr(VI) species were observed on biochars surface confirming the Cr(VI) removal process by reduction and direct adsorption of Cr(VI) ions. Hence, this study provides an excellent option for the application of magnetic biochars to treat Cr(VI) containing wastewater.

Photopolymerization and characterization of vinyl imidazole based allyl derivative polymers; Cr3+ and Cd2+ metal adsorption and antibacterial studies

AbstractA new type polymeric adsorbent, poly(allylphenol‐co‐hydroxyethyl methacrylate‐co‐vinyl imidazole) (PAHV), is synthesized in this study. 2‐Hydroxyethyl methacrylate is used as complementary monomers along with 1‐vinyl imidazole and allylphenol monomers. The photopolymerization method is preferred as a synthesis method and benzophenone is used as the photoinitiator. The effectiveness of the PAHV against bacterial species such as Escherichia coli and Staphylococcus aureus is investigated by the Clinical and Laboratory Standards Institute (CLSI) disk diffusion method. The inhibition areas of PA1H1V3 and PA1H1V1 derivatives against E. coli and S. aureus are measured as 25 mm ± 0.25 mm and 7 mm ± 0.1 mm; 20 mm ± 0.25 mm, and 5 mm ± 0.1 mm, respectively. Sorption efficiencies (%) at pH = 6 (selected optimum pH) for 100 μg/L Cd and Cr of the PA1H1V1, PA1H3V1, and PA1H1V3 derivatives are found to be 69.0 ± 2.7 and 58.3 ± 6.7, 66.8 ± 6.2 and 75.8 ± 5.5, and 97.2 ± 3.7 and 97.7 ± 3.2 (n = 3), respectively. Adsorption studies revealed that the PA1H1V3 polymer can be used as an alternative for the sorption of cadmium and chromium. The pseudo‐second‐order model and Langmuir isotherm model fits for both adsorption processes. The adsorption capacities obtained from the Langmuir isotherm model for chromium and cadmium sorption are 52.63 and 68.49 μg g−1, respectively.

Chromium sorption on synthetic and natural rock minerals with emphasis on speciation behavior and kinetic model using Cr51

Abstract The presence of chromate in the aquatic environment poses toxicity and pollution to the environment. Therefore, the needs to establish methods to get rid of this species is a must. The effect of different natural rock minerals; pyrite, magnetite, pyrrhotite, and wurtzite as constituent parts of the Earth’s crust can play a major role in waste treatment. The properties of those minerals towards the behavior of chromium (sorption) were studied under the effect of changes of pH and contact time to treat the waste solution of toxic chromate. The total chromium species in the reaction system was determined using Cr51 as a simpler, faster and more accurate analytical tools. Concerning the effect of types of minerals, the synthetic ones, the results indicated that pyrrhotite and wurtzite were highly effective for the removal of chromate with almost 100 % sorption capacity as it was pH-independent, despite the presence of a degree of reductive ability of both minerals. While, it was 99 % at pH 8.5 and 28 % at pH 3 for pyrite and magnetite, respectively, which was pH dependent. The equilibrium adsorption capacities for chromium adsorption were 0.34 ± 0.15, 0.028 ± 0.01 and 4.27 ± 1.3 mg/g mineral for natural minerals pyrite, magnetite and synthetic one pyrhotite, respectively. However, it was found 117.7 ± 10.9 mg/g for synthetic mineral wurtzite. These results can be attributed to the redox power of oxide and sulfide minerals; magnetite and, pyrite used. For kinetic studies of chromium (VI) adsorption, non linear model approved that the reaction could be described based on pseudo-second-order kinetics in such simulated environmental heterogeneous systems.

Pyrolytic Modification of Avocado (Persea americana) Peel for the Enhancement of Cadmium(II) and Chromium(VI) Sorption Properties

The sorption process of chromium(VI) and cadmium(II) onto avocado peel (AP) and its pyrolyzed version (PAP) was carried out. The pyrolysis process was investigated in a tube furnace under inert gas conditions (argon) using a temperature equal to 750 °C. A constant mass of used materials and metal solution volume of 0.5 g and 20 cm3, respectively, were chosen for the investigation of the sorption process. Different isotherm models were fitted to describe the process parameters. According to the obtained results and the model that provided the best fit according to the correlation coefficient R2, the removal process is best described by the D-R model (R2 = 0.993 and 0.918; qd = 5.78 and 6.02 mg/g) for Cr(VI) and the Freundlich for Cd(II) ions (R2 = 0.999 and 0.911; Kf = 0.2712 and 0.2952 (mg1−(1/n)(dm(31/ng−1))) for AP and PAP, respectively). The highest level of adsorption capacities reached 6.0 (AP)–7.1 (PAP) and 9.7 (AP)–10.3 (PAP) mg/g for chromium and cadmium ions, respectively. The kinetic modeling showed that in all of the adsorption processes, the best-fitting model was the pseudo-second-order kinetic model, suggesting the occurrence of a chemical reaction between ions and the surface of the used materials.

Sorption of cadmium, chromium, lead, and vanadium from artificial wetlands using Lemna aequinoctialis

The efficacy of the lesser duckweed, Lemna aequinoctialis (Welw.), to remediate varying concentrations of cadmium, chromium, lead, and vanadium from an organo-metallic contaminated media was tested in artificial surface wetland mesocosm experiment. A 100 g of fresh-weight duckweed was introduced into each of the mesocosm, except for the control setup and monitored for 120 days while the metals removal rate was quantified using an atomic absorption spectrometer. A time-dependent and partial sorption of metals was observed with the highest removal rate recorded for cadmium (71.96%), followed by lead (69.23%), vanadium (55.22%), and chromium (41.64%). The uptake and bioaccumulation of metals were reflected in the increased plant biomass (p < 0.05, F = 97.12) and relative growth rate (p < 0.05, F = 1214.35) in duckweed. A coefficient (r 2) of 0.951, 0.919, 0.970, and 0.967 was recorded for cadmium, chromium, lead, and vanadium respectively, indicating that the remediation of metals followed the first-order kinetic rate model. This study highlights the efficacy of the lesser duckweed to preferentially remediate metals in an organo-metallic complex medium for potential wastewater treatment in the petrochemical industry.

Efficient removal of Cr (VI) from aqueous solution using memory effect property of layered double hydroxide material

Treating wastewater containing pollutants with layered double hydroxide (LDH) material attracts excellent interest. LDH materials are known by the memory effect property, which leads to the reconstruction of the LDH structure after its calcination and rehydration. In this study, LDH material was prepared, calcined, and then rehydrated in an aqueous Cr(VI) solution. XRD, FTIR, and SEM-EDS analysis confirm the successful reconstruction of LDH-loading chromium on its surface and layered space. Response surface methodology (RSM) results showed that LDH mass, contact time, and chromium concentration are the main factors controlling the removal of Cr(VI). The heterogeneous sorption of chromium was described by fitting the equilibrium data to the Freundlich model. Analytical techniques, thermodynamic data, activation, and adsorption energies confirm that the removal process of Cr(VI) is endothermic, spontaneous, and physical nature. LDH exhibits good reusability performance with only a 7% reduction of initial adsorption capacity after five cycles of the calcination-rehydration process. These results show that the memory effect of LDH is helpful for the intercalation and the removal of emergent pollutants, especially for wastewater treatment.

Obtaining and study of physical-chemical properties of porous materials based on kaolin

The object of research is kaolin from the Hlukhovetsky deposit (Ukraine). On its basis, granulated sorbent materials were obtained with the addition of various amounts of cellulose as a pore former. After forming the samples, they were dried and fired at a temperature of 800 °C. The obtained granules with a size of 8–9 mm were modified with zero-valent iron. The physicochemical, including sorption properties of granular composites were studied. Using scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDS), the morphology of the obtained samples was investigated and the presence of zero-valent iron particles on the surface and in the pores of the sorbents was confirmed. Based on desorption experiments, it was determined by chemical analysis that the Fe0 content in modified samples with increased pore former content increases from 0.01 g/g of granules for a sample containing 1% cellulose to 0.016 g/g for a carrier with 3 % pore former. The specific surface area and pore volume of the samples were determined by the method of low-temperature adsorption-desorption of nitrogen. Thus, with an increase in the content of the pore former in the ceramic mass, the specific surface of both unmodified and modified samples slightly decreases. Thus, with a cellulose content of 1 %, it is 20 m2/g and 17 m2/g, respectively. When the pore former is increased to 3%, these values are 15 m2/g and 12 m2/g. After applying a layer of zero-valent iron on porous granules, the volume of pores decreases, which is due to the formation of agglomerates of iron particles during synthesis. The study of the sorption capacity of the obtained sorbents with respect to Cr(VI) from model solutions containing a mixture of metal cations (copper, cadmium, cobalt, zinc) showed that granular materials exhibit sorption capacity for metal anions, even in the presence of cations. The amount of chromium sorption naturally increases for modified samples with an increase in the cellulose content in them. However, for model solutions that do not additionally contain metal cations, the sorption value is somewhat higher. Thus, for a sample with a 3 % pore former content, the sorption value is 0.7 mg/g and 0.9 mg/g, respectively, at an initial chromium(VI) concentration of 10 mg/g. The obtained experimental data indicate that the obtained porous granular sorbents based on kaolin can be used in the further treatment of wastewater from electroplating enterprises, which contain a mixture of pollutants in both anionic and cationic forms.

Optimization of Chromium(III) Sorption by Activated Sludge Using Response Surface Methodology

Increased level of chromium due to the anthropogenic activity in environment poses significant threat to human health. This study aims to optimize the removal process of Cr (III) in aqueous solution using activated sludge as adsorbent. Response surface methodology was employed to assess the removal efficiency considering cumulative effect of pH and contact time. The optimal removal efficiency of Cr (III) onto activated sludge was determined as 25.64 mg/g at pH = 4 and 5 g/L biomass dosage. Furthermore, the quantitative relationship between Cr (III) uptake and variable parameters was used to optimize the control level of each parameter by a full factorial design method. The analysis of variance demonstrates that the model was very significant statistically. It shows also that the removal of Cr (III) was affected by the studied factors. The model was statistically tested and verified by experimentation. Therefore, it‘s clear that the response surface methodology gives not only valuable information on interactions between the evaluated parameters but also leads to identify the optimum values of the studied factors. The results obtained will be helpful for improving and understanding the removal process of heavy metals and will lead to develop an efficient process for cleaner environment.

Removal of chromium (VI) heavy metal ions through biosorption using betel seeds from aqueous solution

&lt;p&gt;The reduction of highly toxic Cr (VI) from industrial wastewater of low concentration by different low-cost ample sorbent materials was investigated. In order to remove Cr (VI) from aqueous solutions, the biosorption properties of natural waste (Betel Seeds) were investigated with varying several parameters like contact period, sorbent dose, sorbate sorption, and pH. The study's contact period, biosorbent dosage, sorbate concentration, and pH were all varied from 0 to 120 minutes, 12 g/l, 40 mg/l, and 2 to 7, respectively. According to the study, chromium sorption by betel seed powder reached equilibrium after 60 minutes, and a small change in chromium removal effectiveness was then noticed (Gode, et.al., 2003). At pH 3 and doses of 12 g/l and 30 mg/l of sorbent and sorbate, the maximum removal of chromium (99.2%) was achieved. The results revealed that chromium(VI) biosorption follows the Langmuir isotherm comparison with a correlation factor of 0.998. Additionally, the biosorption process's kinetics adheres to the pseudo-second-order kinetics model, with a rate constant of 0.721 min-1 and the rate constant was evaluated at 30°C. Hexavalent chromium in water was quantified using a UV-VIS spectrophotometer. A desorption examination was also carried out, and it is vital by 0.5H2SO4. Results indicate that the cheap, readily available, widely cultivated sorbent can be used to effectively remove chromium ions.&lt;/p&gt;&#x0D;

Varying growth behavior of redox-sensitive nanoparticles on 1:1 and 2:1 clay surfaces: Mechanistic insights on preferential toxic ions removal in mono, co, and multi-metal contaminated waters

In the current study, contrasting growth behaviour of redox sensitive Fe0 nanoparticles (nZVI) was observed on different clay surfaces i.e., 1:1 non-swelling kaolinite (K-nZVI) and 2:1 swelling bentonite (B-nZVI). Osmotic swelling of bentonite led to Fe0 nucleation and growth of 5–7 nm size particles in the broadened interlayer spaces. B-nZVI had negative zeta potential due to the domination of the surface charge of bentonite clay. In contrast, kaolinite has shown dominant surface growth of nZVI particles (>24.8 ± 7.4 nm) and positive zeta potential, suggesting domination of Fe0 nanoparticles (nZVI) characteristics. This surface-dependent variation led to higher and faster removal of oxy-anions with K-nZVI, i.e., chromium and arsenic (87.5 and 157.35 mg/g) than B-nZVI (18.4 and 86.9 mg/g). In comparison, B-nZVI has shown higher sorption of cations i.e., nickel and cadmium (36 mg/g and 46 mg/g) than K-nZVI (25 and 27 mg/g). XPS and pXRD analysis of reaction precipitates confirmed reductive sorption of chromium, co-precipitation/ complexation of arsenic, electrostatic attraction and complexation of nickel and cadmium as major removal mechanisms. Drastically higher total contaminant sorption capacities of B-nZVI (327 mg/g) and K-nZVI (372 mg/g) in multi-contaminant (Cr + As + Ni + Cd) solutions than individual capacities in mono-ionic solutions was due to co-operative effects and newer sites induced via sorption and redox-transformation of other ionic species. K-nZVI removed chromium and arsenic to below drinking water permissible limits whereas B-nZVI succeeded in separating nickel and cadmium to drinkable levels in groundwater, freshwater, river water, and wastewater samples, emphasizing their applicability in high cationic—low anionic and low cationic-higher anionic species contaminated waters, respectively.

Critical Level of Chromium for Rice in Different Soil Type

The increasing number of industries and poor treatment of waste will damage environmental health, including agricultural land. Agricultural products from contaminated soil may contain hazardous heavy metals such as chromium which can be harmful to human health if consumed. Examination and determination of chromium critical level in paddy soil are required to evaluate the threshold of heavy metals to disable to distribute into paddy plants. This study aims to obtain the critical level of chromium in light and heavy textured soils with paddy as a plant indicator. The pot experiment was carried out at the greenhouse using a completely randomized design with two factors are heavy metal concentration (Cr) and soil texture (A) and five times repeated. The chromium adsorption test uses the Langmuir approach method. Chromium sorption in heavy-textured soil is higher than in light-textured soil. The maximum sorption of chromium metal in light-textured soil is 87.719 mg kg-1, while in heavy-textured soil is 204.082 mg kg-1. Total chromium in the soil decreases after harvest and reduces rice yields. The critical level of light-textured soil chromium in rice was 0.861 mg kg-1, while the critical level for heavy-textured soil Chromium in rice was 1.012 mg kg-1.

Batch adsorption and process optimization for sequestration of Cr(VI) from aqueous solution using biofilm forming filamentous fungus Aspergillus niger BSC-1

Chromium (Cr) contamination in an aquatic environment is one of the greatest concerns nowadays. However, biosorption by various microorganisms is proven to be an environmentally sustainable method. The present study investigated fungal biofilm-mediated sorption of hexavalent chromium [Cr(VI)] using manglicolous filamentous fungus Aspergillus niger BSC-1 obtained from the Indian Sundarban mangrove ecosystem. Biosorbents, such as fungal pellet and fungal biofilm, were utilized for Cr(VI) sequestration. The result showed significantly higher removal of Cr(VI) by fungal biofilm (97.81 ± 2.5 %) than the fungal pellet (79.14 ± 2.4 %) (P < 0.05; two-way ANOVA). Batch adsorption study showed that the highest removal efficiency was attained at 40 °C and pH 3 with 3 g/L of fungal biofilm. The adsorption isotherms, kinetics and thermodynamic analysis suggested monolayer, endothermic and chemisorption of Cr(VI) on the fungal biofilm biosorbent. The adsorption process was further optimized using response surface methodology (RSM) - Central Composite Design (CCD), suggesting the quadratic model for Cr adsorption with high significance (P < 0.0001). The 3D surface plots among the three key variables, i.e., pH, temperature and Cr concentration, revealed that maximum sequestration (92.39 %) was achieved at 40 °C, pH 3 and 30 mg/L of Cr(VI) using 3 g/L of fungal biofilm. Regeneration study demonstrated that fungal biofilm retained 87.19 ± 3.23 % of Cr(VI) sorption with no significant reduction in Cr(VI) removal after five successive adsorption-desorption cycles. X-ray photoelectron spectroscopic analysis showed that adsorption, reduction and complexation mechanisms were involved in Cr(VI) detoxification. Furthermore, the fungal biofilm biosorbent efficiently removed approximately 100 % of Cr(VI) from leather effluent within 90 min of reaction time.

Polyacryl-dimethyl-heptadecanamine-Mullite as a promising sorbent for chromium and vanadium sorption from ilmenite

The growing global demand for economic vanadium and chromium metals has prompted numerous studies into their recovery from ores and various other effluents. The polyacrylic 16,16-dimethyl-heptadecanamine-Mullite adsorbent (P(AA-co-PJMT/Mullite)) was formed by polymerizing acrylic acid in the presence of Mullite and an organic solvent containing the active groups responsible for binding processes with the desired materials using free radical gamma irradiation. The sorbent was fully described using EDX, SEM, FT-IR, XRD and DTA-TG to determine its shape and chemical composition in order to characterize the interplay with the V and Cr ions. The monolayer sorption capacities of V and Cr ions on the prepared sorbent are obtained at 161.64 mg g−1 (3.173 mmol g–1) and 112.61 mg g−1 (2.166 mmol g–1) respectively, using the optimized sorption parameters of feed solution pH 4.0, stirring time 60 and 90 min for V and Cr ions, metal ion concentration 500 mg L−1, sorbent to feed solution ratio 1/1000 (g mL−1), and room temperature (25 ± 2 °C). Sorption kinetics and isotherm studies indicated that the sorption of V ions on P(AA-co-PJMT/Mullite) matched with the Langmuir isotherm, whereas Cr ions matched with Freundlich. The sorption reaction fitted well with a pseudo-second-order kinetic model, demonstrating the chemisorption interaction between metal ions and the sorbent. The thermodynamic results demonstrated that the sorption processes are spontaneous and endothermic. EDTA is used to efficiently desorb V and Cr ions from the loaded sorbent instead of mineral acids, which has a detrimental effect on the decomposition of the Mullite content in the synthesized sorbent. The P(AA-co-PJMT/Mullite) sorbent successfully recovers V and Cr ions from two effluent solutions.

Adsorption of the dye Acid Blue 158 premetalized with chromium on chitin/chitosan

Removal of the premetalized dyes from the effluents of textile and leather industries is still open. The work aims to investigate functional groups taking part in the sorption of premetalized dye Acid Blue 158:Cr on chitin/chitosan and to investigate the mechanism of the sorption. The process was spontaneous (negative value of the Gibbs function), endothermic (ΔH = 0.2679 kJ/mol) with an affinity between the AB 158:Cr and chitin (ΔS = 1.315 J/mol*K).Langmuir, Freundlich, and Dubinin-Radushkevich isotherms were used to approximate experimental data giving a good correlation. Maximal capacity was evaluated as 46.1 mg/g and 370.4 mg/g for chitin and chitosan, respectively. Kinetics was described with a pseudo-second-order model. It was shown that physical sorption and chemisorption can occur parallelly: chemisorption on amine groups via interaction with chromium and physical sorption on amine group or hydroxyl group via interaction with the azo core of the dye.

Molecular mechanisms of Chromium(III) sorption by organo-ferrihydrite coprecipitates induced by crop straws

Agricultural organo-ferrihydrite (Fh) coprecipitates (OFCs), resulting from the coprecipitation of Fe(III) and dissolved organic carbon (DOC) from returned straws, significantly affect the bioavailability of heavy metals in farmland. However, the molecular sorption mechanisms of Cr(III) by the OFCs remain unclear. Here, we explored the sorption behaviors of Cr(III) by the OFCs formed with wheat or maize straws derived-DOC (wheat-DOC or maize-DOC) under various environmental conditions, and further underlying molecular sorption mechanisms using Cr K-edge X-ray absorption near edge structure (XANES) spectroscopy. Results showed that high C loadings reduced the specific surface areas (SSAs) and Cr(III) sorption capacities of the OFCs, implying the blockage of binding sites by C loading. Additionally, although the wheat-DOC induced OFC had a smaller SSA than the maize-DOC induced OFC, their Cr(III) sorption were comparable, which was likely to be compensated by the more carboxyl in the wheat-DOC. Moreover, at a higher ionic strength, the increased or slightly decreased Cr(III) sorption indicated that the inner-sphere sorption was dominant regardless of high or low C loadings, which was also supported by the extremely low Cr(III) extraction percentage. The Cr K-edge XANES spectroscopy suggested that Cr(III) could be immobilized by both the Fh and organic fractions, with the Fh fractions playing a significant role. These findings contribute to a molecular-level mechanistic understanding of Cr(III) sorption by the OFC, which will aid in the prevention and control of Cr-contaminated agricultural soils.

Surface Complexes of Cr(VI) by Eucalyptus Barks

The sorption mechanism of hexavalent chromium sorption on eucalyptus barks was evaluated as a function of solution pH for different adsorbent dosages, surface coverage, and the amount of adsorbent. The chromium retention was evaluated based on the distribution coefficient (D), and this retention is attributed to species, which is predominant between pH 1 and 6.5. The biosorption of Cr(VI) ions onto barks achieved at pH 2.0 in the highest sorbet conditions corresponding to [Cr(VI)] = 10–5 mol (V = 100 mL) is examined for various surface coverage. The surface complexes formed between chromate and eucalyptus barks were found to be &gt; S (HCrO4) and &gt; S (CrO4). Logarithmic stability for log K1–1 and the log K10 values of the complexes were measured and found to be -5.93 in acidic medium and -0.76 in alkaline medium, respectively. Pointed out that the adsorption of Cr(VI) on eucalyptus bark was greater than 90% in all cases, Cr(VI) recovery is strongly acidic dependent and shows maximum retention, for various sorbent amounts, at pH around 2, and this retention is attributed to species, which is predominant between pH 1 and 6.5, the morphological surface of eucalyptus barks were examined by Scanning Electron Microscope (SEM) connected to a micro analyzer EDS.

Modified low cost engineered biochar prepared from neem de-oiled cake for heavy metal sorption

In this work, the sorption of nickel, chromium, and copper metal ions from an aqueous solution was tested using low-cost engineered neem de-oiled cake biochar (ENDCB). The characterization of ENDCB was performed by BET and SEM techniques. The potential parameters effects such as adsorbent dosage (1–5 g/L), temperature (25–60 °C), contact time (15–120 min), and metal ion concentration (25–150 mg/L) of copper, chromium, and nickel were performed on the batch mode. The greater removal percentageof copper, nickel, and chromium was noticed at a contact time of 60 min, initial concentration of 100 mg/L, the adsorbent dosage of 5 g/l, and temperature of 30 °C as 93.3%, 85.4%, and 96.6% respectively. Among various regenerating agents, maximum desorption percentage (92.3% copper, 84.23% nickel, and 95.5% chromium) was noticed at 0.8 M H2SO4.The ENDCB showed stability up to 3 cycles.

Hexavalent Chromium Sorption by Modified Cellulose Macro and Nanofibers Obtained from Eucalyptus Residues

Superparamagnetic Iron Oxide Nanoparticle Nanodevices Based on Fe3O4 Coated by Megluminic Ligands for the Adsorption of Metal Anions from Water.

The uptake ability toward arsenic(V), chromium(VI), and boron(III) ions of ad hoc functionalized magnetic nanostructured devices has been investigated. To this purpose, ligands based on meglumine have been synthesized and used to coat magnetite nanoparticles (Fe3O4) obtained by the co-precipitation methodology. The as-prepared hybrid material was characterized by infrared spectroscopy (IR), X-ray diffraction, thermogravimetric analysis, and scanning electron microscopy combined with energy-dispersive X-ray analysis. Moreover, its magnetic hysteresis properties were measured to evaluate its magnetic properties, and the adsorption kinetics and isothermal models were applied to discern between the different adsorption phenomena. Specifically, the better fitting was observed by the Langmuir isotherm model for all metal ions tested, highlighting a higher uptake in arsenic (28.2 mg/g), chromium (12.3 mg/g), and boron (23.7 mg/g) sorption values if compared with other magnetic nanostructured materials. After adsorption, an external magnetic stimulus can be used to efficiently remove nanomaterials from the water. Finally the nanomaterial can be reused up to five cycles and regenerated for another three cycles.
