Electrophoretic technique in the study of mixed ligand complexes metal nitrilotriacetate adenine system

, : Electrophoretic technique in the study of mixed ligand complexes metal nitrilotriacetate adenine system. Acta Chimica Hungarica 125(2): 295-302

A new method, involving the use of paper electrophoresis, is described for the study of mixed-ligand complex systems in solution. The method is based upon the migration of a spot of metal ion under an electric field with the complexants added to the background electrolyte at fixed pH. The concentration of the primary ligand [NTA] was kept constant while that of the secondary ligand [adenine] was varied. The plot of log [adenine] against mobility was used to obtain information on the formation of mixed complexes and to calculate its stability constants. The binary equilibria M(II)-adenine and M(II)-NTA have also been studied since it is a prerequisite for the study of mixed complexes. Experimentally obtained log K values are 5.81, 4.72 and 4.57 for mixed complexes of UO2(II), Ni(II) and Zn(II), respectively, at .mu. = 0.1 and 35 .+-. C.
