摘要/Abstract

摘要： 提出用Keesom势描写气体分子间的相互作用,应用统计力学理论研究吸附作用,推导出实际气体的吸附等温方程式,该等温式能较好地描述实验吸附等温线.同时指出,BET吸附等温式是实际气体吸附等温式在忽略气体分子间相互作用情况下的极限形式.

关键词: 等温吸附, 实际气体

Abstract: In this paper, we depict the interaction between gas molecules by the Keesom, potential, and study adsorption by the application of statistical mechanics, from which we deduce the adsorption isotherm equation. We find that the theoreti cal isotherm agrees with the experimental one, and that the equation of BET is its limit form, when the interaction between gas molecules is negligible.

Key words: isotherm adsorption, real gas
