利用正己烷萃取-湿法消解-电感耦合等离子体-质谱(ICP-MS)测定印刷电路板中的有机锡.对ICP-MS测定条件进行了最佳化的选择,选取铟作为内标物,实验表明无机锡不溶于正己烷中.与气相色谱质谱法(GC-MS)对比,本方法可实现有机锡的快速测定.该方法的回收率、精密度和检出限分别为85.6%-96.8%、2.6%-6.5%和0.5mg/kg.

A method for the determination of organotin in printed circuit board by ICP-MS with n-hexane extraction and nitric acid digestion has been developed.The detection condition of ICP-MS was optimized and indium was selected as internal standard.Inorganotin can hardly be dissolved in n-hexane.ICP-MS method for the determination of organotin is more quickly and simple with satisfatory results than GC-MS method.The recovery rates, the precision and the detection limits of the method are 85.6%-96.8% ,2.6%-6.5% and 0.5mg/kg,respectively.
