摘　　要：本文在参照粗铅中铅的测定标准分析方法的基础上,对铅的测定方法进行了改进。直接加入掩蔽剂消除铅测定中干扰元素对铅的干扰,用此方法对铅铋合金中的铅进行了准确的测定,取得了很好的准确度和重现性。On the basis of referring the State Standard for determination of lead in crude lead, an improved method for determination of lead was reported in this paper. In this method the masking agent is directly introduced into the determination to eliminate the interference of interfereing elements. With this method accurate determination of lead in lead-bismuth alloy was reached. This method is reliable and has good recurrence.
