Studies on the Determination of Arsenic (VIII)

Yachiyo Kakita and Michiko Namiki


Abstract:

Reduction of arsenic was studied by the use of chromous, titanious and molybdenum solutions reduced with liquid zinc amalgam. Arsenic was reduced to metallic state with chromous solution in hydrochloric acid or hydrochloric acid solution containing sulfuric acid but not with titanous or molybdenum solution reduced. Arsenic obtained by reduction was estimated by iodimetry and gravimetry. Appling this method, the arsenic in iron was determined accurately and rapidly.
