Parameters Affecting Performance Of Arsenic Adsorbtion By Magnetic Graphene Oxide

Abstract

Water is the most essential substance for all life on earth and a precious resource for human civilization. Reliable access to clean and affordable water is considered one of the most basic humanitarian goals and remains a major challenge for the 21^st century.  Adsorption is one of the most effective approach to clean water by removing toxic pollutants. Grapheme oxide/Iron oxides hybrid are recently used by few researchers for the purpose of removing arsenic from waste water   

In this study, Magnetic grapheme oxide was synthesized by co-precipitation method and used as an adsorbent for arsenic removal from aqueous solution. The structures and properties of the grapheme oxide, magnetic grapheme oxide was investigated by X-ray diffraction, Fourier transformed infrared spectroscopy, FTIR.  Batch laboratory tests were conducted to evaluate removal efficiency. Additionally, as (III) adsorption capacity of synthesized materials were studied. The highest percentage of removal is obtained between pH7.5 and 10.5.
