Biosynthesization of ferrous sulfide and its performance on reductive dechlorination of chlorophenol
摘要
Abstract
In order to remove chlorophenols cost-effectively, ferrous sulfide ( FeS ) is chosen for reductive dechlorination reactions. In this study,FeSparticleswere biosynthesized by using Shewanell-aoneidensis as the inoculum. Furthermore,batch experiments are conducted to explore the character- istics of reductive dechlorination of chlorophenol by FeS.Scanning electron microscopeand transmis-sion electron microscopeanalysis of the biogenic FeS reveales that the pellets are composed of a large number of scattered FeS nanoparticles with lamellar structure. X-ray diffractionand X-ray photoelec-tron spectroscopy results show that the biogenic FeSparticles are consisted largely of amorphous FeS and poorly crystalline mackinawite. The biogenic FeS can enable fast dechlorination, confirming a significant contribution of the biogenic FeS to 4-chlorophenol bio-reduction resulting from its good dispersion and relatively high dechlorination activity.关键词
