【摘要】 为了研究氧化石墨烯（graphene oxide,GO）对染料分子的吸附作用,选用甲基橙（Mmethyl orange,MO）和亚甲基蓝（methylene blue,MB）两种有机染料为目标分子,考察甲基橙/亚甲基蓝的初始浓度、吸附剂的用量对吸附性能的影响。采用紫外可见吸收光谱仪测定吸附后有机染料的吸光度值,寻求最佳吸附条件与吸附量。当甲基橙浓度为25mg·L^-1,体积为30m L,氧化石墨烯的质量为20mg时和亚甲基蓝浓度为240mg·L^-1,体积为25m L、氧化石墨烯的质量为10mg时,氧化石墨烯的吸附量分别可以达到5.427和543.29mg·g^-1。实验结果表明:氧化石墨烯对亚甲基蓝染料的吸附性能优于甲基橙。更多还原

【Abstract】 In order to study the adsorption properties of graphene oxide（GO）, Mmethyl orange（MO） and methylene blue（MB）were used as the target molecules to study the initial concentration of dye molecules and the amount of GO on the adsorption performance. The absorbance values of treated organic dyes were measured by UV-Vis absorption spectroscopy（wavelength 200～800 nm）. The graphene oxide functional groups were measured by Fourier transform infrared spectroscopy before the adsorption treatment, in order to find the optimum adsorption conditions and adsorption capacity. When the concentration of methyl orange is 25 mg·L^-1 and volume is 30 mL, the mass of graphene oxide is 20 mg, and the concentration of methylene blue is 240 mg·L^-1, volume is 25 mL, the mass is 10 mg, the adsorption capacity of graphene can reach 5.427 and 543.29 mg·g^-1 separately The experimental results show that the adsorption performance of graphene on methylene blue dye is better than that of methyl orange.更多还原
