摘　　要：实验表明在 SDS 中添加高于其临界胶团浓度的 TX100,可使混合体系溶液对外加电解质的敏感性降低。降低的幅度随 TX100浓度的增大而增大.从理论上对其电导行为进行计算的结果表明,2种表面活性剂分子间存在弱相互作用,混合胶团中较多的非离子表面活性剂降低了胶团对反离子的束缚度,因而混合体系溶液对电解质的敏感性降低.实验还表明。低碳脂肪醇对SDS 水溶液电导行为的影响与 TX 100类似.The sensitivity of mixed surfactant aqueous solution to electrolytes is obviously lowered.The sensitivity is decreasing with the increase of TX100.The results calculated by applying the nonideal solution theory and the experimental data of surface tension are paral- lel to those of the conductive experiments observed.In addition,it is proved by experiments that the effects on SDS aqueous solution conductivity by lower fatty alcohols bear analogy to that of the addition of TX100.
