摘要
通过浸渍 -共沉淀法 ,在SiMCM -41分子筛表面负载氧化铈 ,制备出对水体中氟离子具有特效选择吸附作用的新型除氟材料。研究了表面负载量、溶液的 pH值和温度等对氟离子在除氟剂表面吸附的影响。并就氟离子在除氟剂表面吸附动力学、吸附等温线和吸附机理进行了探讨。
Cerium(Ⅱ) oxide, coated on the surface of SiMCM-41, through wetness impregnation-coprecipitation method, was used to adsorb F-anion in water. It has been discovered that many factors affecting adsorption of F-anion onto the material included concentration of F-anion, pH value and temperatures. Additionally, the adsorption dynamics, isotherms and mechanism for F- ion onto the material were discussed in this paper
