Synthesis of Attapulgite Fiber-Aerogel Composite and its Oil Absorption Capacity under Low Temperature
Attapulgite fiber-aerogel composite was synthesized using sol-gel technology combining with surface modification and conventional drying to overcome the brittle disadvantage of traditional aerogel. Attapulgite fiber was added in the process of sol into gel, in order to enhance the mechanical property of SiO2 aerogel. Hydrophobic and low density fiber-aerogel composites were obtained in this experiment. Investigation of the removal of attapulgite reinforced SiO2 aerogel to TPH in water under low temperature was also carried out. The results showed that the attapulgite fiber-aerogel composites we obtained in this study had good performances of mechanical and hydrophobic properties; the removal rate of aerogel to TPH was 91.02% under the temperature of 10°C.
