摘要：In this paper, the micellization of anionic surfactant sodium dodecyl sulphate (SDS) and cationic surfactant N - dodecylpyridinium chloride (D PC) in aqueous solution at various temperatures has been reported using conductivity measurements. The thermodynamic parameters of micellization ; the free energy, 0 mic Δ G , the enthalpy, 0 mic Δ H , and the entropy, 0 mic Δ S were calculated from the critical micelle concentration (CMC) at different temperatures. T he results show that the CMC of surfactants decreases to reach a minimum and then increases with temperature. Also, the thermodynamic parameters of micellization are discussed
