The stability constants of copper(II) and cobalt(II) with methionine and cysteinewere determined by paper ionophoretic technique. Beside binary, mixed ligand complexes have also been studied, in which methionine and cysteine act as primary and secondary ligand, respectively. The stability constant of Cu(II)-methionine-cysteine and Co(II)-methionine-cysteine mixed ligand complexes were found to be 2.80+ -0.07 and 2.44+ -0.11 (logarithm of stability constant values), respectively at ionic strength 0.1 M and temperature of 35 graduate C.
