Studies on the Determination of Arsenic. VI : Determination of Arsenic in Bismuth, Antimony and Tin

The determination of arsenic in non-ferrous metals was studied by means of iodometry and of colorimetry after it had been separated in metallic state. In this report, the influence of bismuth and antimony on the molybdenum blue coloration was experimented, and the condition of reduction with stannous chloride and the separation of arsenic in bismuth, antimony and tin metal solutions were described in detail and analytical procedures for arsenic in respective metals were proposed.
