摘要
本文利用Ｚｎ￣（２＋）在示波图上有敏锐的切口变化并可指示示波滴定终点的性质，报告了用钼酸铵释放法示波滴定铅锡合金中铅含量的新方法。木方法不用外加指示剂，共存组分不干扰测定，本文进行了多种样品中铅含量的测定，结果令人满意。
The paper reports a iiew method inwhich ammonium modybdate iS released totitrate the lead content in lead-tin alloy as these is appearomee of an acute notch on thedE/dt-E curve ofZn￣(2+) at the titration endpoint.The method does not need the addi-tion of indicator and the other common com-ponents do not interfece with the determina-tion.The method has been used in the deter-mination of lead tin various samples, andsatisfatory results are oftained.
