摘　　要：文章研究铅离子在桑色素一酒石酸盐体系中的极谱波，提出一个新的测定铅的极谱分析法。当铅离子浓度在0．008-0．32μg·mL^-1范围内，导数示波极谱峰高与浓度呈线性关系。许多共存离子不干扰，不用分离直接测定钴合金中微量铅，获得满意的结果。Polarographic wave of lead in the system of morin-tartrate has been examined. A new polarographic method of determination of lead has been produced. There is a linear depen- dence of derivative oscillopolarographic peak height on lead concentration over a range of 0.008-0.32μg.mL^-1. Many kinds of coexisting ions can be tolerated. The proposed method has been applied to the direct determination of micro amounts of lead in the cobalt alloys with satisfactory results. Any separation is not need.
