在进行柱层析分离时,常用硅胶或氧化铝填充在层析柱中作载体使用。我们最近试用“ADST”吸附剂代替硅胶来进行柱层析分离,取得了较好的效果。“ADST”吸附剂化学成份如下:StO_272·12％;Al_2O_312·39％,其余为CaO,MgO及TiO_2等。由于其中SiO_2及Al_2O_3总含量高达85％左右,我们设想能否将它用以代替硅胶或氧化铝应用于柱层析分离工作中,或许它兼有硅胶和氧化铝的性能。在这种思想的 In the column chromatography, the commonly used silica gel or alumina packed in the column for carrier use. We recently tried “ADST” adsorbent instead of silica gel column chromatography, and achieved good results. “ADST” adsorbent chemical composition is as follows: StO_272 · 12%; Al_2O_312 · 39%, the rest of CaO, MgO and TiO_2. Due to the fact that the total content of SiO 2 and Al 2 O 3 is as high as 85%, we envisage whether it can be used as a substitute for silica gel or alumina for column chromatography. Perhaps it combines the properties of silica gel and alumina. In this mindset
