摘要：

A sensitive and highly selective spectrophotometric method is described for the determination of 12-120-mu-g of copper using 6-phenyl-2,3-dihydro-asym-triazine-3-thione (PDTT) as a complexing agent. The red 1:4 water soluble complex was measured at 540nm, epsilon = 1.26 x 10(4) 1. mol-1. cm-1. The method was applied for the determination of copper in standard steels (B.C.S.) and estimation of the solubility product of copper (I) iodide. Comparison was also made with the 2-2' biquinoline method.
