| Abstract: | A composite nano-material(MIP-GON)was prepared by coupling multi-layer surface imprinted silica nano-particles(MIP)with graphene oxide(GO).The adsorption property of MIP-GON for Bisphenol A was investigated.The experimental results showed that the adsorption equilibrium of BPA by the composite adsorption material was reached within 35 mins.The adsorption isothermal was well fitted by the Langmuir model,with a maximum adsorption capacity of 338.3mg/g.The composite material has fairly good selectivity for Bisphenol A comparing with its structural analogs.The absorption efficiency of the material was pH dependent,with optimal absorption around pH of 6.In addition,low temperature was favorable for the adsorption process.The material has excellent cyclic adsorption properties. |
