The catalytic hydrogen wave of arsenic(Ⅲ) in the presence of cobaltous salt has been investigated. Under optimum conditions (0.4 M Na2SO4,10-4M CoSO4,4.5×10-2 M tartaric acid, pH 3-4) the catalytic peak current may be used to determine arsenic as low as 4×10-7 M. Molybdenum and antimony do not interfere.
