A recent technique involving the use of paper electrophoresis is described for the study of equilibria in binary complex systems in solution. The stability constants of the ML and ML2 complex species of some metal ions, namely beryllium(II) and cobalt(II), with hydroxyproline were determined in 0.1 mol L-1 perchloric acid and a temperature of 35 °C. The logarithm stability constants of the ML and ML2 complexes of hydroxyproline were found to be 7.39 ± 0.07 and 5.90 ± 0.03, and 4.73 ± 0.08 and 3.71 ± 0.11 for the beryllium(II) and cobalt(II) complexes, respectively.
