| 摘 要： | 用电导法测定了293K下十二烷基磺酸钠水溶液的活度系数．根据Kohlraush经验公式外推得到极限摩尔电导，经Debye—Hucker和Osager—Falkenhangen公式计算出293K下十二烷基磺酸钠的平均活度系数．结果表明：在表面活性剂小于CMC的范围内其溶液的平均活度系数几乎不变．

| Abstract: | Introduction of electricity determined by sodium dodecyl sulfate on 293K of activity coefficients in aqueous solution. According to Kohlraush empirical formula has been extrapolated molar conductivity limit, the Debye-Hucker and Osager-Falkenhangen formula to calculate sodium dodecyl sulfate on 293K the average activity coefficient. The results showed that the CMC of surfaetant is less than its solution within the scope of the average activity coefficient is almost unchanged. |
