- Abstract
The subject of this study concerns the effect of temperature and Cetyltrimethyl ammonium bromide (CTABr) in the presence of tetramethylammonium bromide [(Me)4N+Br-] at different temperature using conductometric method. CTABr showed a remarkable decrease in critical micelle concentration (CMC) in the presence of [(Me)4N+Br-]. The CMC values reduced to a certain minimum in all cases, with increase in the system temperature at different concentration of [(Me)4N+Br-]. The thermodynamic parameters (δGm0, δHm0 and δSm0) for the micelle system were estimated by applying the phase separation model while the data obtained allowed access to their usability on the micellization process. Enthalpy - entropy compensation was observed, with a constant compensation temperature of 296K.
