摘　　要：采用非醇盐法和常压干燥工艺,以硝酸铝为前驱体,制备了铝基气凝胶材料。考察了无水乙醇用量,甲酰胺用量,环氧丙烷用量对凝胶化时间的影响。采用傅立叶变换红外光谱仪(FTIR)、透射电子显微镜(SEM)和氮气吸附-脱附仪对铝碳基气凝胶的表观基团、形貌和结构等进行表征。此外,考察了铝基气凝胶对橙黄Ⅱ染料废水的吸附性能。结果表明,该类气凝胶具有低成本、易操作、吸附性能佳等优势,在工业污染废水处理等领域具有潜在的应用价值。Aluminum based aerogel was successfully prepared using non-alkoxide raw material(aluminum nitrate)by ambient pressure drying.The effects of amount of anhydrous ethanol,formamide and propylene oxide on the gelation time were investigated.This aluminum aerogel was characterized by Fourier transform infrared spectroscopy(FTIR),transmission electron microscopy(TEM)and nitrogen adsorption-desorption apparatus.Moreover,the orange yellowⅡdye adsorption performance of aerogel was also investigated.These results show that aluminum aerogel has the advantages of low cost,easy operation and good adsorption performance,so it has potential application value in industrial wastewater treatment and other fields.
