Determination of Conductivity of Surfactant Activity Coefficients of Dilute Aqueous Solutions

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 surfactant is less than its solution within the scope of the average activity coefficient is almost unchanged.
