Quantitative indication of the process of forming a complex comes from the evaluation of the stability constants which characterize the equilibria corresponding to the successive addition of ligands. A technique involving the use of paper electrophoresis is described for the study of binary complex system in solution. The first and second stability constants of metal(II) - sarcosine complexes were found to be (7.82 ± 0.07, 6.90 ± 0.03); (3.54 ± 0.11, 1.96 ± 0.02) and (7.41 ± 0.06, 5.57 ± 0.03) (log stability constant values) for Cu(II), Mn(II) and UO2(II) complexes, respectively
