Preparation of Aluminum-based Aerogel by Non-alkoxide Method and Its Adsorption Properties for Anionic Dyes
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 yellow Ⅱ dye 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.
