加入碱金属盐合成超微沸石
Applied Chemical Industry(2007)
Abstract
采用水热合成法,用工业水玻璃作硅源,考察了各种碱金属盐、晶化时间、晶化温度和搅拌速度对合成超微低硅沸石的影响,经X射线衍射、红外光谱、扫描电镜、激光粒度分析和吸附量的测定证实,合成配比取Na2O∶Al2O3∶SiO2∶H2O=3∶1∶2∶185,在晶化温度90℃、晶化时间5 h、搅拌速度3 000 r/min(成胶)和1 500 r/min(成核)的合成条件下,加入0.1 mol NaF,沸石粒度由常规法合成沸石的2μm减小为180 nm;吸附总量由普通沸石的0.25 mg/L增加为0.26~0.272 mg/L;5 min吸附量由0.13 mg/L增加为0.2~0.22 mg/L。
