| Abstract: | 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. |
