Abstract

Background and Aim: Water resources contaminated with arsenic results from industrial or agricultural activities that causes many environmental problems. One of the mechanisms for arsenic removal from aqueous media is the surface adsorption process. In this study, walnut shell chemically activated by zinc chloride, sulfuric acid, potassium permanganate was used for optimization. Powdered activated carbon produced by iron oxide nanoparticles, and Fe3O4 magnetite were prepared by depositing iron on activated carbon to remove the toxic metal arsenic from aqueous media.
Procedure: The synthesis of PAC-AC/Fe3O4 was prepared by chemical co- precipitation method and the physical and structural properties of the adsorbent were analyzed by FESEM-EDX, TEM and FT-IR techniques. Then the effect of pH changes (2-10), contact time (15-240 minutes), amount of adsorbent (0.02-0.1 g), initial concentration of arsenic (2-12 mg.1) were examined and optimized; isotherm and reaction synthetics were also determined.
Results: The optimal conditions for arsenic removal contained magnetic adsorbent pH=2, and 0.02 g of adsorbent at a 6 mg/l concentration at medium temperature. Also, fit diagrams, Freundlich and quasi-quadratic models were determined as isothermal and kinetic optimal models, respectively. The Freundlich model (R2 = 0.999) yielded the maximum absorption of 33.44 mg.g and second order equation of (R2 = 1).
Conclusion: The present study suggested that the synthesized adsorbent had a high potential for the removal of arsenic contaminants. Walnut shell can be used as a suitable adsorbent because of its waste in the country.
