以粉煤灰为原材料,微波法合成P型分子筛，考察了硅铝摩尔比、pH值、晶化时间等不同条件的影响，得到最佳工艺：n( SiO2)(Al2O3)=4.1, pH值12,晶化时间10min。P型分子筛的钙交换能力为442.46mg CaCO3/g。红外光谱表明产品符合分子筛的骨架振动谱带特征，扫描电镜表明产品晶型较好而且粒度均匀，X射线衍射表明特征峰基本与标准特征峰相似。%ZeoliteP was synthesizedfromsolid waste flyashbymicrowave method. The effect ofsilicon aluminum molar ratio, pH value, crystallization timeand otherconditionswas investigated,and the optimum reaction conditions were obtained as follows:n(SiO2)(Al2O3) = 4.1, pH value is 12, crystallization time is 10min.PreparedzeoliteP exchange capacity to Ca2+is 442.46mgCaCO3/g,infraredspectroscopy show that theproducts comply with bands of molecular sieve, SEM showsthat the products haveuniformparticle size,X-ray diffraction showsthat the characteristic peaks ofthe productsaresimilar with standardmolecular sieve.
