  The apparent active energy of Cr3+ reduction was 37.19～78.37kJ/mol,indicating that the cathodic reduction of Cr3+ was a process controlled byelectrochemical step. The results of cyclic voltammetry and A. C. impedance indicated that the discharge of Cr3+ ions on the cathode wascompleted in two steps: In the first step, the Cr3+ ion obtained twoelectrons and formed an intermediate electrochemically active adsorptiveproduct, in the second step, the adsorptive intermediate product obtainedan electron and was reduced to Cr.

  Cr3+还原的表观活化能为373.19～78.37KJ／mol，Cr3+离子在阴极的还原反应为电化学步骤控制过程；循环伏安和交流阻抗法研究表明，Cr3+离子在阴极分两步进行放电；第一步得到2个电子反应生成吸附态的电活性中间产物，第二步为吸附态中间产物得到1个电子进一步还原成Cr。
