Existing and prospective sorption technologies for the removal of arsenic in water

The present article is devoted to a review of existing and emerging sorption technologies for the removal of arsenic in water. After presenting the traditional sorbents used in arsenic removal, experimental studies to characterize the adsorptive capacities of sorbents are detailed. In a second part, metal-loaded polymers, which are among the prospective technologies for arsenate and arsenite removal in drinking water, are introduced. Finally, the design of new metal-loaded polymers to treat arsenic in drinking water is discussed.
