摘要
本文研究了三氧乙基化十二醇醚磺酸钠〔C12H25OC2H4)3SO3Na,简称C12EO3S〕与十六烷基三甲基溴化铵(CTAB),十二烷基三甲基溴化铵(DDTAB)复配体系在纯水溶液中的表面活性,计算了1=1复配体系胶束形成和表面吸附的标准自由能ΔG^0mic、ΔG^0ad,及分子间相互作用参数β^m、β^s,揭示了两组分相互作用的强度和混合体系表面相及胶团的组成。
Surface activities of the composites for trioxyethylenated dodecyl alcohol sulfonate (C12EO3S) and hexadecyl trimethyl aminium bromide (CTAB) and dodecyl trimethyl amininum bro-mid (DDTAB) are studied in aq. solutions at 25℃. Standard free energies (△G°mic, △G°ad) of mi cellization and surface adsorption and molecule interaction parameters (βm,βs) for the 1∶1 composites of C12EO3S-CTAB and C12EO3 -DDTAB are calculated. The results declared the interactiou strength and composition of the composites in surface phase and micelle.
