The interaction parameter indicates that strong interaction exists both in the surface adsorption layer and in the micelle. The strength of the interaction is similar to that of conventional alkyl quaternary ammonium salt/ alkyl sodium sulfate mixed system. 相互作用参数的数值表明,bola分子与SDS在胶团中和溶液表面都发生了强烈的相互作用,这种相互作用的强度与普通季铵盐/烷基硫酸钠混合体系相当。
