Abstract

The coulometric determination of tripositive arsenic and antimony by electrogenerated iodine in a NaHCO~3~ buffered solution of pH 8 has been described. The end point can be determined visually using starch as an indicator. Quantities of As(III) and Sb(III) down to the microgram level can be determined within permissible limits of error.
