摘要
The mixtures of alkylpyridinium chloride (C (n) PC, n=14, 16) and Triton X-100 were studied over the entire mole fractions at 298.15 K. For each mixture, CMC was obtained from surface tension measurements. To estimate the interaction parameter values (beta), the calculation of the monomer concentrations and the mole fractions of the individual surfactants in the mixed micelles, the CMC data were used by applying the regular solution theory. The obtained results showed that the increase of the chain length of C (n) PC led to the stronger preferential incorporation of cationic surfactant in mixed micelle. The large values of |Delta G (o) | confirmed that mixed micelle of C16PC and Triton X-100 was significantly favorable.
