摘要
本文提出用Lennard—Jones势描述气体分子间的相互作用,应用物理力学理论研究吸附.推导出实际气体的吸附等温方程式,并指出当忽略分子间相互作用时,它就变成BET吸附等温式.同时还给出等温吸附常数C的微观表观式.
In this paper, we propose to depict the interaction between gas molecule by Lennard-Jones potential, and to study adsorption by the application of physico-mechanics, from which we deduce the adsorption isotherm equation; we also point out that it become the adsorption isotherm equation of BET, when intermolecular forces can be negligible. The micropic expression of the constant C in both adsorption isotherm is deduced, too.
