摘      要：Using N-methyl-D-glucosamine(NMDG)as the functional monomer,glycidyl methacrylate(GMA)as the connecting monomer,functionalized Fe3O4 nano-particles(NPs)as the support,three adsorbents were prepared including direct polymer GMA-NMDG,magnetic GMA-NMDG polymer(MGN),and boron magnetic ion-imprinted polymer(BMIIP).Based upon the optimization of synthesis conditions,the prepared adsorbents and intermediate products were characterized using Fourier transform infrared spectroscopy,thermogravimetric analysis,scanning electron microscope,energy dispersive spectroscopy,X-ray diffraction,vibrating sample magnetometer,and Brunauer–Emmett–Teller to investigate the synthesis process,the morphological structure and the functional properties of the *** optimum performances of GMA-NMDG,MGN and BMIIP were obtained in the initial neutral solution(pH of 6.5).Moreover,GMANMDG and MGN reached the maximum adsorption capacity at 120 min,whereas BMIIP reached adsorption saturation at 60 *** pseudo-second-order kinetic model was more suitable for the adsorption of boron using the *** maximum adsorption capacity of GMA-NMDG was found to be 43.4 mg·g^(-1),while those of MGN and BMIIP were 32.5 and 28.3 mg·g^(-1),*** Langmuir isotherm model was more appropriate to describe the adsorption *** adsorbents maintained satisfactory adsorption performance within a certain temperature *** ions had little effect on the adsorption of boron,and would be adsorbed simultaneously,due to which,the effect of co-adsorption can be *** adsorption capacity of GMA-NMDG was high,while the adsorption selectivity of BMIIP was much ***,BMIIP showed good adsorption after five cycles of adsorption and *** comparison of adsorbents showed that GMA-NMDG had the highest adsorption capacity and was suitable for *** had a high adsorption capacity,good comprehensive performance and magnetic *** had better ads
