ResumoAbstract D.c. polarography was used to establish the equilibria existing in Cu(II), Ni(II) and Co(II) systems with d -glucosamine and d -galactosamine. The results clearly indicated the formation of 1:1 complexes, ML, and allowed calculation of the stability constants of some complexes. The present results completed very well the potentiometric and spectroscopic data obtained earlier. The reduction mechanisms and the electrochemical behaviour of the formed complexes were also established.
