Stability constants ML and ML2 type binary complexes of Cu (II)/ UO2(II)/ Ni(II)/ Co(II)/ Zn(II)/ Cd (II), 8-Azaguanine system is determined by paper electrophoresis. The technique is based on the movement of a spot of metal ion under an electric field with the change of pH of back ground electrolyte at ionic strength 0.1 M perchloric acid. The stability constant of the ML and ML2 complexes of metal - 8-Azaguanine have been found to be (7.65, 5.50), (7.38, 5.75), (5.64, 3.82), (5.75, 3.68), (5.33, 4.21) and (4.45, 3.73) for Cu (II)/ UO2(II)/ Ni(II)/ Co(II)/ Zn(II)/ Cd (II) complexes respectively.
