摘要：The chemical equilibria of multinuclear complexation of toxic metal ions Cd (II) and Pb (II) with 2-Amino-3-(4-hydroxyphenyl) propanoic acid and 2, 4-dihydroxypyrimidine ligands in aqueous solution were studied bypotentiometric technique. The metal ligand formation constants of investigated binary, ternary and quaternary metalchelates were determined at 3710C and fixed ionic strength I =0.1M NaNO3 by using SCOGS and the complexformations were studied on the basis of computer analysis. Solution structure and stability order of studied binary(MA, MB) ternary (MAB) and quaternary (M1M2AB) complexes have been discussed.
