摘要
通过测定溴离子在两种不同石墨电极上的循环伏安曲线及电流效率,探索了溴离子在石墨电极上氧化的电解条件,比较了两种石墨电极对溴离子电氧化的影响。研究发现,由于电极材料的不同和析氧反应的存在,两种电极材料对溴离子氧化的催化作用有一定差别。溴离子在石墨电极上氧化的电流效率一般在80％以上,最高可达88.5％。
The cyclic voltammogram and current efficiency of anodic oxidation of Br- on two kind of graphite electrode were measured, and the electrolytic conditions for Br- oxidation on graphite electrodes were explored and the oxidation of Br- on two different graphite electrodes were compared. The results show that the two electrodes differ to some degree in terms of the performance in the oxidation of Br-, which can be attributed to the difference in electrode material and to the evolution of oxygen. The current efficiency of the Br- oxidation on graphite electrodes is normally over 80% with the highest being 88. 5% .
