• 中文摘要： The mixed ligand complexes of Cd(II) and Pb(II) with thiosulphate as a primary ligand and chloride, bromide or iodide (individually) as a secondary ligand have been polarographically investigated at 30.degree.C and at a constant ionic strength of .mu .=1.0M(NaClO/sub 4/). Two mixed ligand complexes were formed with the Cd(II) ion: log.beta./sub 12/=4.77, 5.30 and 6.78 for the chloride, bromide and iodide ions, respectively; and log.beta./sub 21/=5.36, 5.04 and 6.22 for the same ions. For the Pb( II)-Ts-Cl system, only one mixed ligand complex was formed with a log stability constant log.beta./sub 21/=4.35. For the Pb(II)-Ts-Br system, three mixed ligand complexes are obtained with log.beta./sub 11/=3.63, log.beta./sub 12/=4.51 and log.beta. /sub 21/=4.85.
