摘　　要：以新疆哈密钾长石为硅源前躯体,十六烷基三甲基溴化铵为模板剂分别通过高温煅烧与水热法合成了介孔分子筛。采用XRD,SEM,FT-IR,Raman,BET等测试方法表征了两种方法合成的介孔分子筛的微观结构和吸附性能。上述研究结果表明:水热合成法比高温煅烧法合成的介孔分子筛具有较好的微观结构与性能。当其晶化时间为96h,pH为10.5时,合成的介孔分子筛的吸附性能最好。Mesoporous molecular sieve was synthesized via Hami potassium feldspar as silicon source precursor, CTAB as template agent by high temperature calcine and hydrothermal synthesis method, respectively. The microstructure and properties of the sieve were characterized by XRD, SEM, FF-IR, Raman, BET, respectively. The results showed that the sieve synthesized by hydrothermal method had better microstructure and adsortption than that of the sieve synthesized by high-temperature calcine. When the crystallization time of the sieve was 96 h and its was pH 10. 5, the sieve had the opti- mum adsorption.
