|
摘要
依托科研项目,设计了羧基化氧化石墨烯对Cu(Ⅱ)的吸附的研究性综合实验。该实验包括羧基化氧化石墨烯材料的制备和其对Cu(Ⅱ)的吸附性能研究,涉及红外光谱仪、拉曼光谱仪、X射线粉末衍射仪、元素分析仪以及原子吸收分光光度计的使用。通过实验,使学生了解石墨烯材料的制备过程和表征技术,提高学生学习兴趣,培养学生创新思维,锻炼学生实践能力,提高学生的综合素质和科研创新能力。
Based on the research projects,a comprehensive experiment on the adsorption of the carboxylic graphene oxide for Cu(Ⅱ)is designed.This experiment includes the preparation of the carboxylic graphene oxide and the study of the adsorption performance for Cu(Ⅱ),which involves the use of the infrared spectrometer,Raman spectrometer,X-ray powder diffractometer,elemental analyzer and atomic absorption spectrophotometer.Through the experiment,the students can understand the preparation process and characterization technology of graphene materials.At the same time,the students' learning interest is improved,their scientific research enthusiasm is inspired,their innovative thinking is cultivated,and their practical ability is trained,so as to improve their comprehensive quality and innovative ability of scientific research.
