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、亚硒酸钠等能使氢在铬电极上的极化曲线明显负移,说明它们有明显的阻氢效果。Cathodic polarization curves were determined when surfactant was used singly or mixed with others under the condition of pH=2.3 at room temperature. The results show that chemicals such as sodium diphenylaminesulfonate, rhodamine B, sodium citrate, methyl naphthylamine and sodium selenite could obviously cause movement of the polarization curves in the negative direction if the scanning electriode potential was lower than -0.85V, indicating that they had an obvious anti-hydrogen effect.
