【摘要】 研究了在318.15 K下硫酸钠和磷酸钠对CTAB-AS-H2O复配体系在稀溶液区相行为的影响.研究表明在水溶液中或在0.10 mol.kg-1钠盐水溶液中,CTAB-AS复配体系均可形成两个双水相区.钠盐的加入使得双水相区及非均相区的面积增大,双水相区向其邻近的各向同性溶液的单相区方向迁移,相区面积增大幅度及双水相区迁移幅度与盐的种类有关.更多还原

【Abstract】 The effects of sodium sulfate and sodium phosphate on the phase behavior of CTAB-AS-H₂O mixed system in dilute aqueous solution region at 318.15 K have been investigated.The investigation indicates that two aqueous two-phase regions can be formed by the CTAB-AS mixed system in pure water or in 0.10 mol·kg^-1 sodium salt brine.The addition of sodium salt results in the enlargement of aqueous two-phase regions and heterogeneous phase region,aqueous two-phase regions shift to the adjacent isotropic single-phase regions,the enlargement extent and shift extent of aqueous two-phase region are related to the kinds of salts.更多还原
