摘要：

The magnetic copolymer was prepared by polymerization of glycidyl methacrylate (GMA) and divinylbenzene (DVB) in the presence of OA-modified magnetic nano-particles. The magnetic strong-base anion exchange resin (MAER) was formed by quaternization of magnetic copolymer. Transmission electron microscope (TEM) and scanning electron microscope (SEM) were used for observation of prepared magnetic nano-particle and MAER, respectively. FT-IR spectrometer was used to characterize the magnetic nano-particle and MAER. To explore the potential application of MAER for natural organic matter (NOM) removal, completely-mixed (CMC) mode was used for humic acid (HA) adsorption. It was found that the HA removal for CMC mode with MAER resin was 10 similar to 20% higher than conventional process before breakthrough.
