摘　　要：研究无机电解质（HCl，KCl，CuCl_2）对蔗糖／邻菲罗啉（Phen）＋硝基乙烷／十二烷基硫酸钠（SDS）＋乙醇的液膜振荡体系的影响．发现电势振荡与SDS阴离子（R_12SO_4^-）在界面上的吸附、脱附的相互关系，结合所测定的表面张力，满意地解释了无机电解质的加入对电势振荡的影响.The effects of inorganic electrolytes (HCl, KCl, CuCl_2) on the oscillation of electricalpotential system (sucrose (aq.)/1 .10-phenanthroline + nitroethane / dodecyl sodium sulfate (aq.)+ ethanol ) were studied The interrelation is found between the oscillation of electrical potential and theadsorption /description of SDS anion (R_12 SO_4 ) on the interface tension, the effects of inorganic electrolytes on the oscillation of electrical potential were satisfactorily explaned.
