以硅溶胶为硅源、十六烷基三甲基溴化铵( CTAB)为模板剂,采用物质的量配比为Ce2O3:SiO2:CTAB:H2O:NaOH =0.015:1:0.45:60:0.48,静态水热合成了Ce-MCM-48分子筛,采用XRD、SEM (EDS)、TEM等方法对其进行了表征,并对其进行了吸附动力学研究.结果表明,本文成功合成了Ce-MCM-48介孔分子筛,其拟一级吸附动力学方程为lg(qe-q)=-0.4365-0.01026t,R2=0.9289,拟二级吸附动力学方程为t/qt =0.4027+0.27818t,R2=0.9999,相对拟一级反应模型,这个结果相关性更好,更能真实地反映分子筛吸附亚甲蓝溶液的反应机理.
