Polarographic study of the coordinated system Zn(II)-glycine-glycinate ion
Abstract:
A polarographic method has been applied to the study of the mixed-ligand system Zn(II)-glycine-glycinate, in aqueous medium, at I= 1.0 M (NaClO(4)) and 25 +/- 0.05 degrees C. The study of the quasi-reversible waves characteristic of Zn(II) has been carried out by means of a new method of analysis proposed by the authors, which is faster and more accurate than the traditional methods. The stabilization of the coordinated species [ZnG](2+) (beta(10) = 2.0), [ZnG(2)](2+) (beta(20) = 0.71), (Zn(G(-))](+) (beta(01) = 7.6 x 10(4)). [Zn(G(-))(2)] (beta(02)= 4.0 x 10(9)) and [ZnG(G(-))](+) (beta(11) = 1.7 x 10(5)) has been established.
