| 摘 要： | 以农业副产物稻壳为硅源、 硫酸铝为铝源, 通过炭化、 碱溶和水热合成工艺, 无需老化过程及添加晶种制备了洗涤助剂P型分子筛, 并考察了硅铝比、 碱度比、 反应时间和反应温度对合成分子筛的影响. 实验结果表明, 分子筛合成的最佳条件为： n(Na2O) ∶n(SiO2)=1.43, n(SiO2) ∶n(Al2O3)=4, n(H2O) ∶n(Na2O)=18.3, 在85 ℃反应8 h. 产品的XRD和SEM表征表明, 上述条件下合成的P型分子筛产品具有较高的结晶度, 无杂相且晶粒细小, 其Ca2+交换容量可达330 mg/g.

| Abstract: | P type zeolite was synthesized by carbonization, alkali dissolving and hydrothermal method with rice husk and aluminum hydroxide as t
he starting materials without aging prouss and adding crystal seeds. It was found that the optimal zeolitization conditions are temperature 85 ℃; time 8 h; n(Na2O) ∶n(SiO2)=1.43, n(SiO2) ∶n(Al2O3)=4, n(H2O) ∶n(Na2O)=18.3. The prepared product showsa calcium ionic exchange capacity of 330 mg/g. XRD and SEM of the product show that pure, single phase and high crystalline zeolite P samples were synthesized under optimum conditions. |
