摘要
采用改进的Hummers法制备氧化石墨烯(GO),利用扫描电子显微镜、X射线衍射仪、傅里叶红外光谱仪及拉曼光谱仪分别对GO进行了表征;以其为吸附材料,探究了GO对正戊基黄药、正丁基黄药和乙基黄药在不同温度条件下的吸附行为。研究结果表明,GO对黄药的吸附符合Langmuir等温吸附模型,提高温度有利于GO对黄药的吸附,该吸附过程为可自发完成,属物理吸附。随着黄药碳链的增长,GO对黄药的饱和吸附量呈递增趋势,且吸附更容易发生。
Graphene oxide(GO)is prepared by modified Hummers method,and GO is characterized by scanning electron microscopy,X-ray diffractometry,Fourier transform infrared spectroscopy and Raman spectroscopy.The adsorption behavior of GO on n-pentyl xanthate,n-butyl xanthate and ethyl xanthate at different temperature conditions is investigated.The results show that the adsorption of xanthate on GO is consistent with the Langmuir isotherm adsorption model.Increasing the temperature is beneficial to the adsorption of xanthate on GO.The adsorption process is spontaneous and is physical adsorption.With the increase of xanthate carbon chain,the saturated adsorption capacity of GO on xanthate is increasing,and adsorption is more likely to occur.
