不同电极材料和不同金属离子添加剂对Cr^(3+)电氧化的影响

Effect of Different Electrode Materials and Addition of Different Metal Ions on Cr^(3+)Anode Oxidation

通过循环伏安和电流效率测量研究了 Cr3+在 Pb O2 、石墨和铂电极上的阳极氧化行为 ,发现 Pb O2 是Cr3+氧化的高活性电极 ;探讨了在电解液中加入 Ag+,Mn2 +和 Co2 +对 Cr3+氧化的影响 ,结果表明 。

By measurements of cyclic voltammetry and current efficiency,the anodic oxidation behavior of Cr 3+ at PbO 2,graphite and Pt electrodes was studied. It is found that PbO 2 is a higher active electrode material for Cr 3+ oxidation. The effect of addition of Ag + ,Mn 2+ ,Co 2+ on Cr 3+ oxidation was also explored. The results indicate that the electrocatalysis of Ag + is very obvious.
