摘要
以金属离子M，2－（3，5-二溴吡啶偶氮-2-）-5-二乙氨基苯酚（3，5-diBr－PADAP）和聚乙二醇辛基苯基醚（OP）的三元络合物为显色体系，用矩阵分光光度（CPA）法研究了共存痕量铜、铋、铁3元素的测定，并对实际铅锭样品中的痕量杂质进行了测定，得到了较满意的结果．
Taking a ternary complex, M-3, 5-diBr-PADAP-OP as color-producing system, a research has been made on the simultaneous determination of Cu, Bi and Fe by spec- trophotometry-CPA matrix method. This method has been applied to determine the trace impurities in a practical lead ingot with satisfactory results.
