【摘要】 测定了各种表面活性剂在pH =2.3、室温条件下于硫酸铵电解体系中单独或混合使用时的阴极极化曲线。结果表明,当扫描电位小于- 0.85V时,二苯胺磺酸钠、罗丹明B、柠檬酸钠、甲萘胺、亚硒酸钠等五种表面活性剂能使氢在铬电极上的极化曲线明显负移,将其用于电解铬时,能明显提高电流效率。
【Abstract】 This paper determines cathode polarization curves when surfactant is used singly or comprehensively under the condition of pH=2 3 in the room temperature The results of the experiment show that such chemicals as the sodium diphenylaminesulfonate, rhodamine B, sodium citrate, methyl naphthylamine, sodium selenite can obviously cause the negative movement in the polarization curves if the scanning electric potential is less than minus 0 85v, which indicates that they have the obvious anti-hydrogen results
