Formation constant of mixed complexes of Cu (II), UO2 (II), Co (II), Zn (II), Cd (II) NTA and Glycocymin was determined by paper electrophoresis. The value of stability constant of studied complexes were found to be 5.35, 5.15, 4.23, 3.67, 3.45, 3.41 for Cu (II), UO2 (II), Co (II), Zn (II), Cd (II) respectively at Ionic strength 0.1M perchloric acid at 35°C.
