摘要
综述了用于活性炭的各种吸附模型。包括最基础的Ｌａｎｇｍｕｉｒ模型，该模型完全忽略吸附质分子间相互作用。ＢＥＴ模型引入了吸附质之间的相互作用而改进了Ｌａｎｇｍｕｉｒ模型。Ｏｕｂｉｎｉｎ理论从１９４７年提出后得到了不断的完善和发展，最近又有新的进展。对１９９７年Ｊｅｎｓｅｎ等人提出的全新的多空间吸附模型（ＭＳＡＭ）也在本文中作了介绍。功能强大的计算机的日益普及导致对活性炭吸附理论的计算机模拟越来越受到重视。本文介绍了一些运用Ｍｏｎｔｅ Ｃａｒｌｏ模拟的最新研究，并就该问题提出了一些建议。
A lot of models for absorption on activated carbons are reviewed in this paper.The most bole approach to absorption is the Langmuir model,which completely neglect the interactions between absorbing molecules. The BET approach improves on the Langmuir model by taking into account absorbing/absorbing interactions. Dubinin's theory, developed in successive stages between 1947 and 1980s, has recently found new applications. Meanwhile, the MSAM by Jensen et al in 1997 is also introduced. The increasing availability of powerful computers has resulted in a rapid increase in computer simulation of adsorption processes in activated carbons. Some advances studies using the Monte Carlo simulation approach are introduced and a couple of proposals are made this issue.
