| 摘 要： | 合成Fe2O3纳米粒子复合纤维素膜.采用XRD、TEM和磁力线等多种方法对Fe2O3纳米粒子复合纤维素膜的结构和性能进行表征,并研究Fe2O3纳米粒子复合纤维素膜对亚甲基蓝的降解作用.结果表明：当溶液中H2SO4加量为25.8mol/L、H2O2加量为2.4mol/L时,用5g/L的复合纤维素膜对1.4×10-5 mol/L的亚甲基蓝溶液进行降解,25min内降解率达到100%.

| Abstract: | The cellulose/Fe2O3 nanocomposites fibers were prepared by NaOH/urea aqueous solution with cotton linter pulp and FeCl2·4H2O as reactants.The cellulose/Fe2O3 nanocomposites fibers were characterized by X-ray diffraction（XRD）,transmission electron microscopy（TEM）,and vibrating sample magnetometer（VSM）.The degradation of methylene blue（MB） with cellulose/Fe2O3 nanocomposites fibers was studied.The results showed that the degradation rate of MB could reach 100% in 25 min,when addition dosage of H2SO4,H2O2,cellulose/Fe2O3 nanocomposite fibers and MB were 25.8 mol/L,2.40 mol/L,5.00 g/L,1.40×10-5 mol/L,respectively. |
