摘要
用“锯末法”从铅锑合金锭中取样,并用硝酸和酒石酸的混合溶液溶解样品,再经过适当的处理后,用ICP-AES法测定样品溶液中锑和硒的含量。结果表明,锑的加标回收率为96.2%;硒的加标回收率为92.1%,11次测定的RSD(n=11)小于3.56%。方法操作方便,分析速度快,结果准确。方法已用于铅锑合金产品中锑、硒的测定,取得满意的结果。
The sample was obtained from original sample using ＂sawing method＂ and was dissolved with a mixed solvent of nitric acid and tartaric acid. After the sample solution was pretreated with a series of methods, Sb and Se were determined by inductively coupled plasma atomic emission spectrometry （ICP-AES）. The results show that the recovery of standard addition of Sb was 96. 2% and that of Se was 92. 1%, and that the relative standard deviations（n= 11）were smaller than 3. 56%. The method is efficient, accurate and easy to operate, and has been applied to the determination of Sb and Se in Pb-Sb alloy products with satisfactory results.
