摘要： 提出了一个用气相色谱测定气体在固体表面上吸附停留时间的方法. 经推导, 得到了测定公式.用八种烷烃及苯在硅胶上的吸附实验数据进行验证和研究, 得到了满意的结果.

关键词: 吸附停留时间, 吸附振动时间, 气相色谱, 气固表面

Abstract: A method for determining the sojourn time of adsorption of gas on solid surface by gas chromatography is presented. A theoretical equation has been derived. The method has been verified by the experimental adsorption data of eight alkanes and benzene on silica gel. And satisfactory results were got.
