摘　　要：提出一种迎头色谱程序升温脱附快速测定活性炭吸附热的新方法。本方法是基于Ｐｏｌａｎｙｉ吸附势理论结合程序升温脱附曲线，通过微机采样和数据处理。详细介绍了测定的系统装置、控制条件和操作步骤；测定了许多活性炭对各种有机试剂的微分吸附热与填充度的关系曲线，其结果与前人文献的结果基本一致。测定周期短，操作简易。A new rapid method for determination of adsorption heat of activated carbon was established.This method is based on Polanyis potential theory together with determination of temperature programmed desorption of frontal chromatography curve using microcomputer sampling and data processing.The principle of the method was discussed in detail.The differential adsorption heat versus filling degree of many organic solvents on activated carbons were measured with results similar to those in the reference.Duration of runs for determination was about 1 h.
