摘　　要：采用静态水热晶化法,以硅溶胶为硅源、六亚甲基亚胺(HMI)为模板剂,通过掺杂Ce合成了具有MWW层状结构的Ce-MCM-22分子筛。利用粉末X射线衍射(XRD)、扫描电镜(SEM)、透射电镜(TEM)等方法对其进行了表征,考察了各种因素对Ce-MCM-22分子筛吸附亚甲基蓝溶液的影响,结果表明当Ce-MCM-22分子筛的投加量为0.6 g/L,亚甲基蓝浓度为2.0 mg/L,pH值为7,震荡60 min时,吸附脱色效果较好。Ce-MCM-22 molecular sieve with MWW of layer structure was synthesized by static hydrothermal crystallization method,using silica sol as silicon source,hexamethylene imine（HMI） as template agent.Molecular sieve of Ce-MCM-22 was characterizated by powder X-ray diffraction（XRD）,scanning electron microscopy（SEM）,transmission electron microscopy（TEM）.The effects of various factors on the adsorption of methylene blue solution with the Ce-MCM-22 molecular sieve were tested.The absorption bleaching is better when the conditions of absorption are the Ce-MCM-22 zeolite dosage 0.6 g/L,the concentration of methylene blue 2.0 mg/L,pH value 7 and shock time 60 min.
