Özet

A differential spectrophotometric method has been used for determination of critical micelle concentration (CMC) of alkyl phenol polyglycol ether and lauryl alcohol polyglycol ether. The CMC values so determined are in agreement with the values obtained by other techniques which were used by the same author in previous study.1 The variation with temperature of CMC for these surfactans has been measured. For these solutions, the changes of micellization enthalpies were calculated by using Clasius-Clapeyron equation.
