Sažetak
The complexation of toxic metal Cd(II) with cysteine, as an essential amino acid, has been studied to define the stoichiometric stability constants of Cd-cysteinate complex at 0.59 M ionic strength. Optimal experimental conditions were defined to follow and quantify the formation of Cd-cysteinate complex. The 1:1 molar ratio of Cd to cysteine, and cysteine to Cd, was defined for Cd-cysteinate complex formed under the defined conditions in a DP mode on HMDE. From mass balance equations the stoichiometric stability constants of Cd-cysteinate complex were determined under various titration conditions. Grand average amounts to 5.75E7 M-1.
