ADSORPTION AND CATALYTIC DECHLORINATION OF DDT ON FE-SBA-15

摘要：

In this work, highly dispersed Fe-SBA-15 was successfully synthesized by a hydrothermal and evaporating method, and used for DDT removal in aqueous media. The synthesized materials possess highly ordered mesostructure and good adsorption efficiency, over 98 ％ DDT can be removed from aqueous media in 12 h. After separation and thermal catalytic treatment at a relatively low temperature of 350℃ for 2 h, the trichloromethyl group of DDT adsorbed on Fe-SBA-15 can be completely dechlorinated, whereas on SBA-15, the adsorbed DDT was completely decomposed at 450℃ for 2 h.
