Removal of Arsenic from Water Using Graphene Oxide Nano-hybrids
Abstract In 21st century, providing the fresh and affordable water through protects and purifying the water source from pollutants is biggest and most concern environmental challenges. Toxic element particularly arsenic in water is serious matter of threat for human from many developing countries, and long exposure of arsenic is generally associated with skin lesions and hyperkeratosis like adverse effects. Graphene oxide (GO) and its composites have attracted widespread attentions as novel adsorbents for the adsorption of various water pollutants due to their unique physicochemical characteristics. This chapter presents advances made in the synthesis of graphene oxides and their composites, and summarizes the application of these materials as a superior adsorbent for the removal of arsenic from water. The adsorption affinity in terms of contact time, pH, and temperature has been discussed. Competitive ion effect and regeneration are included within the text. Moreover, the challenges for the commercial uses are discussed.
