摘    要:综述了近些年来在气固吸附理论研究领域对吸附等温线的研究进展。论述了从早期的BDDT的5种类型吸附等温线,到IUPAC的6种类型吸附等温线,再到基于Ono-kondo晶格模型的Gibbs吸附分类的5种类型吸附等温线.讨论了与各种类型吸附等温线类型相对应的吸附机理,并对滞留回环现象进行了解释和分析。

关 键 词:吸附等温线  分类  超临界吸附  滞留回环

Abstract:In this work, advances in the research of isotherms for gas-solid adsorption systems are reviewed. The classifications of adsorption isotherms such as the BDDT classification, the IUPAC classification, and the Gibbs adsorption classification on the basis of Ono-kondo lattice model are also stated. The adsorption mechanism of molecular within micropore, mesopore or macropore of adsorbents corresponding to different kinds of isotherms are discussed. The explanations and analysis of hysteresis loop phenomena of adsorption and desorption are presented as well.
Keywords:Adsorption isotherms  Classification  Supercritical adsorption  Hysteresis loop
