And C_ (12) H_ (25) N ~ + (CH_3) _2CH_2] _2 · 2Br ~ (abbreviated as C_ (12) -2-C_ (12) · 2Br) / C_ (12) H_ (C_ (12) H_ (25) N ~ + (CH_3) _2] _2C_2H_4 (OC_2H_4) _n · 2Br ~ - as the number of ethoxy groups (E) (12) -2-E_n-C (12) · 2Br, n = 2, 3) in the mixed aqueous solution of SDS with C12 The synergistic effect of the two components during the 2Br / SDS mixed micelle formation was predicted theoretically. The total critical micelle concentration (cmc_ (T.mim) = 0.0339mmol·L -1) , The corresponding mole fraction of SDS in solution phase (x_2 ~ (*)) = 0.447. When the SDS molar fraction (x_2) = 0.5 in the aqueous phase, the total aggregation number (N_T) of mixed micelles = 36, the molar fraction of SDS in mixed micelles (x_2 ~ M) = 0.43.
