摘要
本文在用迎头色谱法测定固体微粒物质的比表面的基础上,提出了用此色谱流出曲线直接估算微孔比孔容和平均孔半径的简易方法,实验结果表明,估算值与实验值基本一致。
In this paper, according to frontal chromatographic effluent curve that is used to determine the specific surface of tiny grains such as chromatographic carbon, the simple estimative method that is used to determine the specific pore volume and the mean pore radii has been established. Some different types of samples have been tested. The results of which are agreeable to that obtained by experiment.
