Abstract
Sorbents are disclosed which exhibit less inherent leaching of arsenic and antimony than what is achieved by conventional sorbents. The inventive sorbents are formed by a process which includes the steps of contacting the porous sorbent particulate with a solution of a metal oxide or metal hydroxide, or a metal oxide or metal hydroxide precursor, and depositing metal oxides and hydroxides within the pores of the porous sorbent particulate. Purification of water is also described.
