摘要: 通过循环伏安和电流效率测量研究了Cr3+在PbO2、石墨和铂电极上的阳极氧化行为,发现PbO2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,Ag+对Cr3+氧化有明显的电催化作用.

Abstract: By measurements of cyclic voltammetry and current efficiency,the anodic oxidation behavior of Cr3+ at PbO2,graphite and Pt electrodes was studied. It is found that PbO2 is a higher active electrode material for Cr3+ oxidation. The effect of addition of Ag+,Mn2+,Co2+ on Cr3+ oxidation was also explored. The results indicate that the electrocatalysis of Ag+ is very obvious.

Key words: Cr3+, Electrooxidation, Eletrocatalysis, Cyclic voltammetry, Current efficiency
