| 摘 要： | 采用活性MnO2浸渍、FeCl3浸渍和不同温度下渗硫等方法，对蛭石进行改性，制得一系列改性蛭石吸附剂。采用固定床吸附的方式，对吸附剂的吸附效果进行测试，筛选出2种高效、廉价的吸附剂，它们是活性MnO2浸渍蛭石和FeCl3浸渍蛭石。在分析各种改性蛭石的吸附机理后认为，除有物理吸附功能外，还有化学吸附功能。图6参10

| Abstract: | A series of modified roseite adsorbents were prepared in various ways, including impregnation with active MnO2, with FeCl3 and with sulfur under different temperature conditions. The adsorbing efficacy of the adsorbents were tested by the fixed bench-scale adsorption method; wherewith 2 kinds of highly efficient and cheap adsorbents were picked out, i.e. roseite impregnated with active MnO2 and roseite impregnated with FeCl3. After having analyzed the adsorbing mechanism of the modified roseites, it is opined that, besides physical adsorption, chemical adsorption plays a role too. Figs 6 and refs 10. |
