Abstract Silica aerogel, as a kind of ultralight porous material, has the characteristics of extremely low density, ultra-high porosity and large specific surface area, which is an excellent adsorbent carrier. However,the surface of silica aerogel skeleton is mainly composed of silicon hydroxyl groups, which has poor adsorptive selectivity and low adsorption capacity for pollutants. In this work, an excellent adsorbent was developed by functional modification of silica aerogel with amine group. Anion dye Congo red was used as model pollutant. Results showed that the amine-modified silica aerogel had excellent adsorption performance, of which the maximum adsorption capacity for Congo red could reach 800—900 mg/g according to Langmiur isotherm model in a wide pH range of 3—9. The adsorption kinetics of Congo red on the amine-modified silica aerogel was fast, which could be well described with pseudo-second-order kinetics model, and more than 80% of the maximum adsorption capacity was obtained within 1 h. According to dynamic adsorption experiments, the amine-modified silica aerogel showed excellent dynamic adsorption capacity. Results showed the amine-modified silica aerogel is promising adsorbent for anion dye.

Key words： silica aerogel amine-modification adsorption congo red
