Interaction Parameters of Surfactant Mixtures by Inverse Gas Chromatography

Abstract

The Inverse Gas Chromatography (IGC) has been used in the measurement of surfactant-surfactant interaction parameters at different percentages and temperatures in cationic surfactant mixtures. Specific retention volume values obtained with different probe solutes in surfactant mixtures could be qualitative tests of the miscibility as those obtained in polymeric materials. The results for systems constitute by cationic surfactant mixtures have been compared. Two phenomenological methodology, Farooque-Deshpande and Huang, for calculate of the interaction parameter have been employed and the results compared with those obtained in polymer mixtures. The results obtained in surfactant mixtures are similar to obtained in polymeric material when both methodologies are compared. We found that the difference between interception calculated values are greater when the slope obtained by Huang methodology to withdraw of the unity.
