摘　　要：本文采用ICP-OES测定粗铅中的杂质．再用差减法求出铅含量的分析方法．通过对样品的制备，仪器条件的选择及对杂质元素的确定，建立了用ICP-OES间接测定粗铅的方法．方法快速，简便，适合于粗铅中含量超过92%铅的测定。A difference method of the determination of lead in crude lead by inductively coupled plasma-optical emission spectrometry was proposed. The impurities in crude lead was detected by ICP-OES and then the content of lead was determined by difference method. The method was rapid and simple. It was suitable to the analysis of crude lead, of which the content is beyond 92%.
