摘要:
以微晶纤维素和磁性Fe3O4纳米粒子为原料,四甲基氢氧化铵溶液为溶剂,通过乳化法制备了磁性纤维素微球。利用扫描电微镜、傅里叶变换红外光谱仪、X线衍射仪、振动样品磁强度计、比表面和孔径分析仪对磁性纤维素微球进行分析表征,结果表明磁性纤维素微球确为纤维素包裹Fe3O4纳米粒子形成,且表面粗糙,粒径约200 nm,比表面积13.6 m2/g,表面微孔体积为0.5 cm3/g,磁强度为2.0×10-3 T/g。磁性纤维素微球染料吸附试验表明,在pH 4~ 8时其对亚甲基蓝的去除率最大,达到70%以上。
Abstract:
Magnetic cellulose microspheres were prepared by emulsion method with microcrystalline cellulose and magnetic Fe3O4 nanoparticles as raw materials and tetramethyl ammonium hydroxide solution as a solvent.On the basis of the analyses of the magnetic cellulose microspheres by scanning electron microscope(SEM),Fourier transform infrared spectrometer(FT-IR),X-ray diffractometer(XRD),vibrating sample magnetometer(VSM),specific surface area and pore size analyzer(BET),the magnetic cellulose microspheres were indeed formed by cellulose-coated Fe3O4 nanoparticles,with rough surface,the particle size of around 200 nm,the specific surface area of 13.6 m2/g,the surface pore volume of 0.5 cm3/g and the magnetic strength was 2.0×10-3 T/g.The dye adsorption test of magnetic cellulose microspheres exhibits that the removal rate of methylene blue was the highest between pH 4 and 8,reaching more than 70%.
