摘要
用自装的BET容量法装置测定了几种粒状钛型吸附剂的比表面及其孔径分布。测定是在常温减压下进行的。结果表明:钛型吸附剂在加铀海水中的吸铀量与样品的比表面及孔径分布有一定的内在联系。这种表面性质的研究对吸附剂的筛选有重要的指导意义。
The determination of the specific surface area and the pore size distribution for Ti-type granular adsorbents was carried out with a home-made apparatus based on BET volumetric methods. The determination was proceeded under room temperature and reduced pressure. The results suggest that the amount of uranium adsorbed by the adsorbents in concentrated sea-water is related inherently to their specific surface area and pore size distribution. The research on the surface characteristics of the adsorbents can be a significant guidence for selecting adsorbents.
