Abstract
|
|
|
|
The solubilization of p-chlorobenzoic acid in aqueous solutions of pure cationic, nonionic, amphoteric, and their mixed surfactant systems have been measured by the UV-Vis spectrophotometric method. The effects of hydrophobic tail-group with different chain length and the hydrophilic head-group on the solubilization of p-chlorobenzoic acid have been studied and also thermodynamic parameters have been calculated from the dependence of Ks values on the temperature. The results show that the values of ΔGo for the solubilization by all surfactant systems are negative and the values of ΔHo and ΔSo are all positive.
