表面活性剂水溶液体相与表面相之间的相平衡

Phase Equilibrium Between the Bulk Phase and the Surface Phase of Surfactant Aqueous Solutions

以溶液体相与表面相之间的Ｂｕｔｌｅｒ相平衡关系式为基础，建立了标题系统的相平衡方程。运用此方程计算了Ｈ＿２Ｏ－Ｃ＿（１２）ＥＯ＿３（十二醇三乙二醇醚）、Ｈ＿２Ｏ（０．１ｍｏｌ／ＬＮａＢｒ）－ＳＤＳ（十二醇硫酸钠）及Ｈ＿２Ｏ（０．１ｍｏｌ／ＬＮａＢｒ）－Ｃ＿（１２）ＥＯ＿３－ＳＤＳ三个系统的表面相绝对组成，表面活性剂组分在表面相与溶液体相之间的分配系数，表面活性剂的相对吸附活性以及表面吸附量。结果令人满意。

Based on Bulter￣’s relationship of the phase equilibrium, this paper Suggests a scries equations for the title systems.The calculations for several practical systems were carried out with these equations and the results can be obtained satisfactorily.
