摘要：

Potential-pH equilibria and potentiodynamic polarization studies were used to examine the electrochemical behavior of copper in aqueous ethylenediamine solutions. Potential-pH diagrams for the copper-water-ethylenediamine system were derived at different total copper {Cu-T} and ethylenediamine {En(T)} activities. The diagrams show that the solubility range of copper is significantly extended in the presence of ethylenediamine. Polarization experiments were conducted in deaerated and aerated aqueous solutions of 10(-2) M ethylenediamine with 10(-3) M cupric sulfate, and 10(-4) M ethylenediamine with 10(-5) M cupric sulfate over a wide pH range. The results of these experiments are discussed in terms of relevant potential-pH diagrams. Good correlations were observed. (C) 2002 The Electrochemical Society.
