查询词典 chromium-chlorite

Cyclic voltammetry indicated that there were Cr→Cr, Cr →Cr oxidation reaction on anode, while there were Cr→Cr, Cr→Cr, Cr →Cr deoxidization reaction on cathode. The graphite electrodes treated by acid and heating could enhance the reversibility and kinetic of the electrode reaction. The nature graphite electrodes had been eroded during charge/discharge process, while the graphite electrodes by activation could avoide corroding by hexad chromium ion. The reversibility and kinetic of the electrode reaction of chromium ion on activation electrode had been increased, so which indicated that graphite surface augment oxygenous function corps which could increase electrode hydrophile capability.

循环伏安实验表明：铬液流电池的电极反应非常复杂，在阳极存在Cr→Cr，Cr→Cr的氧化反应，在阴极存在Cr→Cr，Cr→Cr，Cr→Cr的还原反应；热处理的石墨电极和重铬酸钾处理的石墨电极能提高电极反应的活性和可逆性；在充放电实验中未处理的石墨电极发生严重腐蚀；分别用这两种方法处理过的石墨电极具有防止六价铬侵蚀的功能；铬离子在活化处理过的石墨电极上的反应活性和可逆性增加，可以认为：重铬酸钾溶液活化处理和加热处理后的石墨表面的含氧官能团增加，电极亲水性增强。
