Abstract
The stability constants for the equilibrium of complexation between a sugar alpha-amino acid and the divalent metal ions cobalt(II), nickel( II), copper(II), zinc(II), and cadmium(II) have been determined by pot entiometry at 298 K and ionic strength I = 0.1 M in aqueous solution. The complexes observed as well as their stability constants are discus sed in terms of the characteristics of the amino acid.
