| Abstract: | The differences of hydride generation reaction between Sb(Ⅴ) and Sn in various acidity and reducing agent concentration have been studied and a sensitive and rapid AFS method has been developed for the determination of tin in antimony powder and antimony compounds. The detection limit of the method for Sn is 1.0×10-6 and the recovery of standard addition is better than 94%.The precision (RSD, n=4) of less than 6.0% is obtained when the Sn contents are 10-6 level.The method has been applied to the determination of trace tin in antimony samples and antimony compounds with satisfactory results. |
