“…Therefore, there is a stringent need to develop highly efficient technologies to remove arsenic species from groundwater and wastewaters. Removal of arsenic ions is usually performed by nanofiltration and reverse osmosis, electrocoagulation, chemical precipitation, ion exchange, ,− and adsorption. ,,,− Among the most accessed technologies for removal of arsenic, adsorption is obviously the most attractive by its accessible costs, easy operation, and large potential for the development of new generations of adsorbents. ,− …”
