摘要:

固体在液相中的吸附对实际生产和生活都具有重要的意义。研究吸附过程时,通常需要研究吸附热力学,吸附热力学则需要通过吸附热力学参数来分析,即吸附吉布斯自由能变(ΔG)、吸附焓变(ΔH)、吸附熵变(ΔS)。本文从吸附平衡的化学势出发,介绍了不同方法计算吸附热力学参数的推导过程,举例介绍吸附热力学参数的计算和应用。

关键词: 吸附, 热力学, 热力学参数

Abstract:

The adsorption on the solid-liquid interface is important for industry and daily life. To investigate the adsorption process, the adsorption thermodynamics usually are essential. The adsorption thermodynamics are analyzed with the parameters of the change of Gibbs free energy (ΔG), enthalpy (ΔH), and entropy (ΔS). In this presentation, the different methods for calculation of the adsorption thermodynamics parameters are introduced. Moreover, examples for calculations and applications of the adsorption thermodynamics are presented.

Key words: Adsorption, Thermodynamics, Thermodynamics parameter
