Abstract—Kinetics of electrochemical reduction of zinc(II) complexes is studied in a wide range of solution
pH using the polarization measurements and chronopotentiometry. Adsorption of glycinate ions on zinc elec-
trode and complexing of zinc(II) with glycine are studied using the ¹³C NMR method. Based on the experimen-
tal data, the electrochemical behavior of zinc(II)–glycine–water system is considered.

Key words: electrochemical reduction, glycinate complexes of zinc, kinetics
