摘要
本文研究了微分电位溶出法测定环境水中痕量铅的实验条件．结果表明，水样可以不经消化处理而直接测定，方法的精密度高，相对标准偏差≤５．２％，方法的准确度也满足痕量分析的要求，加标回收率为（９７．２～１０８．０）％．
This paper describes the study on the determination of trace lead in environmental water by differntial potentiometric stripping analysis. Results show that water samples may be determined directly without digestion,giving a relative standard deviation of equal or less than 5. 2% and a recovery of (97. 2～108. 0) % by the method of standard additions.
