Abstract

In this paper a modified version of the theory of multilayer phsyical adsorption developed previously by the authors is presented. This new theory is applied to various adsorbent-adsorbate systems and excellent agreements between theoretical results and the observed data are obtained for Type Ⅱ and Type Ⅲ adsorption. In addition, the Type Ⅰ isotherm, which was not accounted for previously, can also be explained in terms of the newly derived isotherm. It is conjectured that two parameters involved in this theory, q/q1 and a, are somehow related to the heat of adsorption.

이 論文에서는 著者들이 앞서 發展시킨 多分子層物理吸着理論을 修正하여 새로운 吸着理論을 提案하였다. 이 새로운 理論을 여러가지 adsorbent-adsorbate 系에 適用시켜 본 결과 Type Ⅱ와 Type Ⅲ 吸着의 경우에는 理論置와 實驗置가 잘 一致하였다. 뿐만 아니라 이미 발표한 理論으로써는 설명할 수 없었던 Type Ⅰ 吸着等溫式도 새로운 理論으로는 說明할 수 있었다. 이 理論에 包含되어 있는 두 parameter q/q1과 a는 吸着熱과 어떤 關聯性이 있는 것으로 推測된다.
