Abstract
Stability constants of complexes of aluminium(Ⅲ) and thorium(Ⅳ) with methionine and cysteine have been determined by modified paper electrophoretic technique at μ= 0.1 M. The proportion of ionic species of methionine and cysteine were varied by changing pH of background electrolyte. The stability constants of the complexes metal-methionine-cysteine have been found to be 4.31 ± 0.12 and 5.40 ± 0.19 (log K values) for Al3+ and Th 4+ complexes, at temperature 35 ℃, respectively.
