Abstract:
The description relates to a composition and a method for reducing the concentration of arsenic in water. Contaminated water is contacted with acid-activated clay characterized by a removal efficiency for arsenic of at least 95 wt %. Following sufficient contact, the water is separated from the acid-activated clay. In preferred form, the acid activated clay is characterized by a BET surface area of at least about 200 m2/gram.
