Calcium-Iron(III)-Doped Alginate Gel Beads for Sorption of Arsenate and Selenate
2001
Systems and methods for removing oxyanionic contaminants, such as arsenate (As(V)) and selenite (Se(IV)), from polluted water. The system utilizes calcium alginate which has been doped with ferric iron. The system is operated as either a batch-type or continuous feed purifier. A dehydrator is included for drying spent absorbent beads to form a dry disposable solid waste product.
