用于水体净化的功能化介孔分子筛的研究
Study on Functionalized Mesoporous Molecular Sieves as Water Purator
【摘要】 本文采用中性模板途径合成了介孔分子筛HMS,并通过化学修饰手段在其孔内壁上接枝了γ氯丙基三乙氧基硅烷,得到功能化的介孔分子筛CPSHMS考察了CPSHMS对三氯甲烷的吸附性能,去除率达97%,最大吸附容量为196mg/g,经其处理过的水体中三氯甲烷浓度低于国标及美国EPA标准
【Abstract】 A kind of mesoporous molecular sieve was synthesized by neutral template method, and the complexity material CPS HMS was prepared by grafting γ chloropropyl triethoxysilane onto its inner surface. The chloroform adsorption characteristic of CPS HMS was studied. The maximum absorption capacity can reach 196 mg/g and the chloroform-removed percentage could amount to 97%.
