本发明阐述的是通过改变膨润土的结构和组成来制取吸附剂的方法。利用硫酸来处理膨润土以制取活化土的方法是众所周知的。按照这种方法,用10—20％的硫酸溶液在90—95℃时处理膨润土6—8小时,然后将活化了的膨润土从母液中分离,洗去余酸和在水解作用下可产生游离酸的硫酸铝,最后进行干燥以制取活化膨润土。 Described herein is a method of making an adsorbent by changing the structure and composition of the bentonite. Processes for treating bentonites with sulfuric acid to make activated earth are well known. According to this method, the bentonite is treated with a 10-20% sulfuric acid solution at 90-95 ° C for 6-8 hours and then the activated bentonite is separated from the mother liquor, the residual acid is washed off and the free acid is produced by hydrolysis Of aluminum sulfate, and finally dried to obtain activated bentonite.
