摘要
采用 ICP/MS法分析酸雨中的 Pb元素 ,在优化的工作条件下 ,研究可能的干扰影响及选择合适的内标元素( Y89) ,同时测定 Pb的同位比以确定大气中 Pb的污染。 Pb的检出限 0 .0 0 2～ 0 .0 0 3ppb,相对标准偏差 0 .0 2 %～ 2 .0 1%
A method for the analysis of Pb in acid rain by inductively coupled plasma mass spectrometry(ICP/MS) was used,the potential interference was investigated and inner standard element was choosed.Isotopic ratio of Pb was measured in order to defining pollution in air.Method detection Limit:0.002~0.003ppb RSD:0.02~2.01%.
