石墨烯介导铁还原菌耦合针铁矿体系降解四氯化碳OA北大核心CHSSCD
Degradation of Carbon Tetrachloride by Graphene Mediated Iron-Reducing Bacteria Coupled with Goethite System
研究了氧化石墨烯(GO)、还原氧化石墨烯(rGO)及双氧水改性还原氧化石墨烯(rGO(H2O2))3种石墨烯介导铁还原菌耦合针铁矿体系的铁还原过程以及该体系强化降解四氯化碳的机理.结果表明:不同石墨烯均能有效促进铁还原菌还原针铁矿和铁还原菌耦合针铁矿体系对四氯化碳的降解,其中rGO的促进作用最为显著,其机理主要与石墨烯表面的醌类等基团具有更强的电子传递能力、吸附态Fe(Ⅱ)浓度高及能生成还原能力强的次生铁矿蓝铁矿等因素有关.
Graphene oxide(GO),reduced graphene oxide(rGO)and hydrogen peroxide-modified reduced graphene oxide(rGO(H2O2))were prepared and their effect on the reduction of Fe(Ⅲ)in a coupled system of iron-reducing bacteria and iron oxides was studied.The formation of secondary minerals and the electron transfer processes in graphene were investigated.The kinetics of carbon tetrachloride degradation by iron-reducing bacteria and iron oxides mediated by graphene was dete…查看全部>>
