摘要
研究了用ＩＣＰ—ＡＥＳ法同时直接测定电解铅中的８种微量杂质元素，用等效浓度法校正铅的基体干扰，研究结果表明加标回收率为９０％～９８％，方法精密度（ｎ＝９）为ＲＳＤ％１６～９８，该方法快速、准确。
Simultaneous direct microdeterminations of eight impure elements in electrowon lead are tested.The equivalent concentration method is employed to correct the matrix disturbance.The test results show that the standard recovery rate ranges from 90 to 98%,the accuracy of the method(RSD%)from 1.6 to 9.8(n=9).The ICP-AES used here is a rapid and accurate method.
