Equilibration processes in alkaline Cu | Cu(II), glycine system

The nature and kinetics of the equilibrium processes at interface between copper electrode alkaline solution containing glycine complexes Cu(II) have been studied. material balance equations that consider formation Сu(I) were used to calculate composition system. It was found amount compounds increases with increasing pH ligand concentration. Using EQCM method it electrochemical dissolution Cu proceeds under open circuit conditions potentials 60–70 mV higher than their values. generation Cu+ ions obeys laws pseudo-first order a rate constant ~2 × 10–4 s–1. is assumed final product equilibration monoligand complex CuL (L– glycinate anion). Besides, there thermodynamic probability cuprous oxide in
