摘要
通过共沉淀法制备了易分离的磁性氧化石墨烯二维纳米吸附材料,并将其用于有机染料的清除,设计了一个综合性实验。所制备材料通过傅里叶变换红外光谱、热重量分析法、粉末X射线衍射和扫描电子显微分析的方法对其进行表征确认。所制备磁性氧化石墨烯对有机染料的吸附清除能力通过测试其对亚甲基蓝的吸附来表征,并引入芬顿体系来评估其降解及回收利用性能。该实验设计可提升本科学生对二维纳米吸附材料的应用认知和环境保护意识,同时为其将来的科学研究奠定一定的基础。
A comprehensive experiment was designed on preparation of separable magnetic graphene oxide 2D-nano-adsorbent by a co-precipitation method,which was utilized for the removal of organic dye.The prepared material was characterized by Fourier transform infrared spectroscope(FTIR),thermogravimetric analysis(TGA),X-ray diffraction(XRD)and scanning electron microscope(SEM).The organic dye adsorption property of the prepared magnetic graphene oxide was tested by methylene blue adsorption;the degradation property and reusability were assessed by Fenton system.The experiment can improve undergraduate students’awareness of 2D-nano-adsorbent application and environmental protection,and lay a certain foundation for their upcoming scientific research.
