摘要
设计了改性纤维素对甲基橙的吸附综合实验。该实验以实验室常用滤纸为纤维素源,利用聚乙烯亚胺(PEI)改性纤维素滤纸(CFP),并对水中甲基橙进行吸附性能研究。通过实验,使学生了解材料表面改性的方法,表征技术以及性能测试,锻炼学生的动手操作能力,激发学生的科研热情。同时,以实验中“普通滤纸”为引线,开发学生的创造潜能,训练学生的发散思维,培养学生的创新能力。
The comprehensive experiment for adsorption of methyl orange by modified cellulose was designed.The polyethylene imine(PEI)modified cellulose filter paper(CFP)were prepared by using the common laboratory filter paper as cellulose source.And the adsorption performance of methyl orange was researched.Through the experiment,the students could understand the surface modification method of materials,characterization and performance test,which could train students’practical operation ability and cultivate and stimulate their interest in scientific research.At the same time,the ordinary filter paper in the experiment is used as the lead to develop students'creative potential,train students'divergent thinking and cultivate their innovative ability.
