摘要： 在Polanyi吸附势理论基础上,结合程序升温脱附曲线的测定,建立了一个快速测定吸附热的新方法。详细讨论了该方法的原理。通过微机采样和数据处理,测定一条吸附热与覆盖度的曲线仅需1h左右。

关键词: 吸附热的测定, 迎头色谱, 程序升温脱附

Abstract: Anew method for the rapid determination of adsorption heat was established.This method was based on the Polanyi′s potential theory together with the determination oftemperature programmed desorption curve. The principle of the method was discussed in detail. By means of microcomputer sampling and data processing,the duration of runs for measuring the curves of the differential heat versus coverage was about 1 h.

Key words: Determination of adsorption heat, Frontal chromatography, Temperature programmed desorption
