测定了硅胶和活性炭自水、环己烷和正丁醇中吸附Triton X-100的等温线。提出了TritonX-100在硅胶-环己烷界面上形成单分子层,在硅胶-水界面上形成双分子层的吸附模型。测定了硅胶自环己烷-正脂肪醇(C_2,C_4,C_8和C_(12))和水-正脂肪醇(C_2和C_4)混合溶剂中吸附Triton X-100的等温线。自环己烷-正脂肪醇中吸附时,醇的烃链越短,浓度越大,降低Triton X-100的吸附作用越显著。自水-正脂肪醇中吸附时,正丁醇降低Triton X-100的吸附作用比乙醇时更显著。但当Triton X-100的浓度较低时,正丁醇(0.5 mol·din~(-3))的存在却使TritonX-100的吸附有所增加。
The isotherms of Triton X-100 adsorption on silica and activated carbon from water, cyclohexane and n-butanol were determined. A monolayer of TritonX-100 was formed at the interface of silica gel and cyclohexane to form a bilayer adsorption model at the interface of silica gel and water. The isotherms of silica gel adsorbing Triton X-100 from cyclohexane-n-aliphatic alcohols (C_2, C_4, C_8 and C_12) and water-n-aliphatic alcohols (C_2 and C_4) When adsorbed from cyclohexane-n-aliphatic alcohol, the shorter the hydrocarbon chain of the alcohol, the greater the concentration and the lower the adsorption of Triton X-100. The adsorption of n-butanol on Triton X-100 was more pronounced than that of ethanol on adsorption from water-n-aliphatic alcohol. However, the presence of n-butanol (0.5 mol · din ~ (-3)) increased the adsorption of Triton X-100 when the concentration of Triton X-100 was low.
