Effective remediation of arsenate from contaminated water by zirconium modified pomegranate peel as an anion exchanger

Abstract Several ways have systematically been employed to modify carbons for removing heavy metal from contaminated solution. In the present study, Fe impregnated pomegranate peel carbon (Fe-PPC) as a green adsorbent was prepared by addition of Fe3+ions into the pomegranate peel followed carbonization. Stability of iron on PPC was examined by releasing of Fe ions in aqueous solution at the pH range of 2–10. The effect of contact time, variable pH, and initial concentration were studied in the adsorption of arsenite and arsenate anions by Fe-PPC. Maximum removal of arsenite and arsenate anions were observed in the pH range of 5–6 and 9–11 respectively which were 76.3% and 100%. The elemental analysis and characterization of As -FePPC were performed by energy dispersive X-ray analysis (EDX) and BET. The adsorption rate (ν0) value indicated that the initial rates are suitable for arsenic anions adsorption on Fe-PPC in aqueous solution. The more than one mechanism was governed by the adsorption arsenate and was chemisorption, while the physical adsorption had the more contribution to the arsenite adsorption.

Water pollution is increasing due to the different factors such as population growth, large-scale urbanization, deforestation, and unethical activities in the river or other sources of water. Various experts have been working in the field of the preparation ofactivated carbon from renewable energy including cost-effective technologies and products in an eco-friendly manner for various applications. This review article discusses methodologies utilized by various experts for the preparation of activated carbon for the abatement of water pollution. Biomasssuch ascoconut shell, Moringaoleifera seed, Peanut shell, Pomegranate peel, Rice husk, Lemon shell, Banana peel, and Orange Peel are found extremely helpful in the field of treatment of the contaminated water. The reviewed literature showed that the Biomass can be isolatespollutants from contaminated water through physical, mechanical, and biological techniques and removes various physicochemical pollutants such as pH, color, DO, turbidity, conductivity, turbidity, chloride, fluoride, TSS, TDS, BOD, COD, nitrate, phosphate, and heavy metal, etc. from contaminated water.

We report the extremely high and selective uptake of selenium oxyanions by a novel anion exchanger, Ni1-xZn2x(OH)2(OCOCH3)2xnH2O (0.15<x<0.25). The tested Ni–Zn basic salt (x=0.24) exhibited very high selectivity for Se(IV) [Kd = 9.0 × 104 cm3/g with an initial Se(IV) concentration of 1 × 10-4 M] in the presence of 0.1 M C1− solution. The uptake of Se(IV) on the Ni–Zn basic salt was irreversible when treated with solutions containing 1 N C1− 1N NO3− or 1 N PO43−This novel exchanger also showed high Kd (2.6 × 103 cm3/g) for Se(VI), and therefore it is expected to be useful for decontamination and removal of selenium oxyanions from contaminated water.

Adsorption is most commonly applied process for the removal of pollutants such as dyes and heavy metals ions from wastewater. The present work talks about preparing graphenic material attached sand grains called graphene sand composite (GSC) by using ordinary sugar as a carbon source. Physical morphology and chemical composition of GSC was examined by using (FTIR, SEM, EDAX and XRD). Efficiency of GSC in the adsorption of organic dyes from water was investigated using reactive green dye with different parameters such as (ph, temperature, contact time and dose). Adsorption isotherm was also studied and the results showed that the maximum adsorption capacity of dye is 28.98 mg/g. This fast, low-cost process can be used to manufacture commercial filters to treat contaminated water using appropriate engineering designs.
