摘要:

文章采用列表对比的方式,简要介绍了微孔吸附常用经典模型的出处、应用范围、发展历史和各自的特点。为了方便系统了解和掌握物理吸附中的微孔经典分析方法,文章将其分成三类:(1) 由标准等温线发展出的方法,包括t-图法、αs-图法、n-图法和MP法;(2) 基于微孔填充理论的方法,包括D-R方法、D-A方法和D-R-S方法;(3) 目前普遍使用的方法,包括原始HK方法(狭缝型孔)、HK-SF方法(圆柱型孔)和HK-CY方法(球型孔)以及三种改进后的HK方法。

关键词: t-方法, MP法, D-R方程, 原始H-K方程, 改进H-K方程

Abstract:

This paper briefly compares the source, application scope, development history and respective characteristics of the commonly used classical models of microporous adsorption. In order to facilitate the systematic understanding and mastery of classical microporous analysis methods in physical adsorption, the methods are divided into three categories: (1) methods developed from standard isotherms, including t-method, αs-method, n-method and MP method; (2) methods based on micropore filling theory, including D-R method, D-A method and D-R-S method; (3) the currently commonly used methods include the original HK method (slit pore), HK-SF method (cylindrical pore), HK-CY method (spherical pore) and the improved HK method.
