摘要
以粉煤灰为原料,采用碱熔酸洗和微波水热合成粉煤灰分子筛(PMS),通过SEM、XRD和FTIR等对分子筛进行了形貌和结构分析。研究表明合成PMS的适宜条件:SiO_2/Al_2O_3物质的量比为3.5,微波加热时间40 min,晶化温度100℃,晶化时间8 h。XRD结果显示为P型分子筛,SEM表明PMS结构规整且粒度均匀。PMS对碱性蓝9(BB 9)的吸附量为652.35μg/g,适合处理染料废水。
Fly ash molecular sieve （PMS） had been prepared by fly ash as raw material through micro- wave hydrothermal method, alkali fused and acid washed. The production was characterized by SEM, XRD and FTIR. It was found that the optimal synthesis process was： the molar ratio of SiO2/Al2O3 was 3.5, micro- wave time 40 min, reaction temperature was 100℃, reaction time was 8 h. XRD indicated that PMS had the structure of P-type molecular sieve. SEM showed that PMS had regular structure and uniform size. The ad- sorptive capacity of PMS was 652.35μg/g for Basic Blue 9. PMS was suitable for treating dye wastewater.
