摘要：

Relations were derived between the retention of metal cations on a cation-exchange column and the composition of a mobile phase in the presence of complexing agents and, based on the derived relations, a method was suggested for measuring the stability constants of complexes of metal cations with anions of dicarboxylic (polycarboxylic) acids. The method was applied to the determination of the stability constants of complexes of some divalent cations (Zn2+, Ni2+, Co2+, Cd2+, Mn2+, Fe2+ and Pb2+) with the anions of oxalic, tartaric, citric, pyridine-2,6-dicarboxylic and malonic acids. The results are in good agreement with those obtained with other methods.
