摘要

采用Hummers法制备了氧化石墨烯,再与贝壳粉进行复合制得氧化石墨烯贝壳粉复合材料(GO/SP),利用扫描电镜、红外光谱等手段对GO/SP的结构和官能团进行表征。考察GO/SP对染料废水的吸附性能,探讨pH、温度、投加量、反应时间、浓度等因素对去除率的影响,确定最佳吸附条件,并对吸附结果进行数据拟合,建立吸附等温模型和吸附动力学模型。结果表明:与SP相比,GO/SP的吸附效果明显提高。SP吸附刚果红的过程符合Langmuir模型,准一级动力学模型,GO/SP吸附刚果红的过程符合Langmuir模型,准二级动力学模型。

Abstract

Graphene oxide was first prepared by Hummers method and then reacted with shell powder to produce GO composite material (GO/SP).The structure and functional groups of GO/SP were characterized by TEM and infrared spectroscopy.The adsorption performance of GO/SP on dye wastewater was studied,the influences of pH,temperature,dosage,reaction time,concentration and other factors on removal rate of wastewater were discussed,and the optimal adsorption conditions were determined.Moreover,the adsorption results were fitted with the data,based on which the adsorption isothermal model and adsorption kinetic model were established.The results showed that the compared with SP,GO/SP had significantly better adsorption effect and exhibited optimal adsorption performance.The adsorption process of Congo red by SP was consistent with Langmuir model (quasi first order kinetic model),while that of Congo red by GO/SP was consistent with Langmuir model (quasi-second-order kinetic model).
