氧化石墨烯的制备及其对罗丹明B的吸附性能
|
摘要
采用改进Hummers法以石墨粉为原料制备氧化石墨烯(GO),利用红外光谱仪、X射线衍射仪和扫描电镜对其官能团、物相结构和表面形貌进行表征分析。研究所制备的GO对阳离子染料罗丹明B(RB)的吸附性能,考察了吸附时间、GO用量、吸附温度和溶液初始pH对吸附性能的影响。结果表明:GO吸附RB的适宜条件为:吸附时间70min、GO用量0.01g、温度30℃、pH=3,GO对RB的最大吸附量为2002.71mg/g。由吸附动力学及等温吸附模型分析可知,GO对RB的吸附符合准二级动力学模型及Langmuir等温吸附模型。
Graphene oxide(GO)was prepared by improved hummers method with graphite powder as raw material.Fourier transform infrared spectroscopy(FT-IR),X-ray diffraction(XRD)and scanning electron microscopy(SEM)were used to characterize the structure of functional groups,phase structure and surface morphology of GO,respectively.The adsorption performance of GO for cationic dye rhodamine B(RB)was studied,and the effects of adsorption time,GO dosage,adsorption temperature and pH of solution were investigated,respectively.The results showed that the optimum conditions for the adsorption were as follows:adsorption time 70 min,GO dosage 0.01 g,adsorption temperature 30℃,and pH=3,the maximum adsorption capacity of GO for RB was 2002.71 mg/g.The adsorption kinetics and isotherm adsorption model analyses showed that the adsorption of RB by GO accorded with Pseudo-second order dynamics model and Langmuir isotherm adsorption model,respectively.
