摘要：

A simple and quantitative method for separating antimony(III) from antimony(V) by coprecipitation with thionalide is described. The total concentration of antimony is determined through addition of tin(II) chloride followed by thionalide coprecipitation and antimony(V) is determined by subtraction. The coprecipitation system was investigated with the use of Sb-122 radiotracer. The precipitate was collected on a membrane filter for neutron activation analysis. The dectection limit of antimony was found to be in the order of ng l-1 under the experimental conditions. The reliability was checked with National Research Council of Canada standard reference material.
