METHOD FOR PURIFICATION OF ARSENIC-CONTAINING WATER TO BE TREATED

摘要

PROBLEM TO BE SOLVED: To provide a method of removing arsenic-containing water to be treated which can stably, easily and highly inexpensively remove arsenic in water to be treated such as ground water. SOLUTION: A biodegradable coagulant composed of a polyamino-acid-radiation crosslinking substance is added into an aqueous solution containing arsenic and ferric components and agitated and thereafter the coagulated solid is separated and removed.
