Effects of silicate, sulfate, and carbonate on arsenic removal by ferric chloride
Abstract Effects of silicate, sulfate, and carbonate on the removal of arsenite [As(III)] and arsenate [As(V)] by coprecipitation with ferric chloride were studied. Silicate significantly decreasedExpand

Chemical reactions between arsenic and zero-valent iron in water.
Batch experiments and X-ray photoelectron spectroscopic (XPS) analyses were performed to study the reactions between arsenate [As(V)], arsenite [As(III)] and zero-valent iron [Fe(0)]. The As(III)Expand
