Preparation of Magnetic Porous Carbon@β-Cyclodextrin/Epichlorohydrin Copolymer and its Adsorption Properties for Polychlorinated Biphenyls
Magnetic porous carbon@β-cyclodextrin/epichlorohydrin copolymer(MPC@β-CDEP)composite is prepared by emulsion polymerization method and its structure and morphology are characterized.The adsorption properties of the material for 8 kinds of polychlorinated biphenyls(PCBs)are investigated.The results show that the adsorption rate of PCBs by MPC@β-CDEP is fast,and the adsorption equilibrium could be reached in 5 min.The results of static and dynamic adsorption show that the adsorption process of MPC@β-CDEP accords with the Freundlich model and the quasi-secondary kinetic model.The adsorption of PCBs by MPC@β-CDEP is mainly chemical adsorption and possesses multi-layer adsorption characteristics.
