Study of Interfacial Properties of HEHEHP in n-heptane

摘要/Abstract

摘要:

对HEHEHP-正庚烷/(H2, Na2)SO4液-液体系的界面性质进行研究, 计算界面吸附特性参数CAC, CminAI 及吉布斯吸附自由能 ΔGad, 发现 Gibbs, Szyzkowski 和Polynomial吸附等温式与实验结果相近, 并对实验结果进行分析和讨论.

Abstract:

The interfacial actirity of HEHEHP at n-heptane 0. 05mol·L-1 (H2, Na2)SO4 interface have been investigated at 293 K. Different adsorption isotherms such as the Gibbs, Szyzkowski and Polynomial have been found as fits well to experimental interfacial tension isotherms. The interfacial adsorption parameter CAC, Cmin, AI and the free energy of adsorption ΔGad have been calculated respectively.
