Abstract
Abstract Metal complexes formed in solution by citric acid or diglycolic acid with calcium, magnesium, zinc or nickel ions have been studied by pH titrations. Normal and protonated complexes of 1:1 stoichiometry are formed, the compositions and stability constants of which are reported which are in best agreement with the experimental data. The effectiveness of these ligands for the sequestration of metal ions is compared with that of NTA.
