An improved method for removing arsenic from aqueous systems containing arsenic

摘要

Disclosed is a method for removing arsenic from aqueous systems containing arsenic which includes contacting said aqueous system with an adsorbent material comprising (i) activated bauxite and (ii) aluminum trihydrate, until the arsenic is substantially removed from said aqueous system. The adsorbent material is prepared by the steps including (i) mixing powders of activated bauxite and aluminum trihydrate in the presence of water to form granules; (ii) drying said granules; and (iii) calcining said dried granules.
