| 摘 要： | 通过溴离子在PbO2、Pt、石墨和2种DSA电极上循环伏安和电流效率的测量,发现各种电极材料对溴离子氧化的催化作用不同,在酸性条件和中性条件下溴离子的氧化情况也有明显差别.溴离子氧化的最佳条件是在中性溶液中使用PbO2电极,电流效率最高可达到96.1%,并且氧化电位较低,氧化电流较大.

| Abstract: | By the measurement of cyclic voltammetry and current efficiency at PbO 2, Pt, graphite and two kinds of DSA electrodes, it was found that the electrocatalysis behaviour of Br - oxidation at different electrode materials is different, the results of Br - oxidation in an acidic solution and a neutral solution are also different. The best conditions for Br - oxidation are to use PbO 2 electrode in a neutral solution, the highest current efficiency is 96.1%, moreover, the initial oxidation potential is lower, but the oxidation current is higher. |
