摘要
基于三嗪基多孔聚合物的合成及其应用于染料吸附的创新性成果设计了综合实验.以碘化钾为催化剂,大大缩短了亲核取代反应合成三嗪基多孔聚合物P(CC-CH)的反应时间,并测定其染料吸附性能,使学生深入认识芳杂环亲核取代反应、催化剂的重要性以及染料废水处理方法,掌握红外光谱仪、X射线衍射仪、紫外-可见分光光度计等表征手段,提高学生的环境污染与防治意识和利用所学知识解决社会实际问题的能力.本实验学时紧凑,仪器表征简便,试剂成本低廉,适合在化学或相关专业的本科实验教学中推广.
Abstract
Based on the innovative achievement in the preparation of a triazine-based porous polymer and its application in dye adsorption,a comprehensive experiment is designed.Potassium iodide was used as the catalyst,greatly shortening the reaction time of nucleophilic substitution reaction to synthesize the triazine-based porous polymer P(CC-CH).Together with its dye adsorption behavior,students can have a deep understanding of the aromatic nucleophilic substitution reaction,the importance of catalyst,and the dye wastewater treatment.Meanwhile,students will master the use of infrared spectrometer,X-ray diffractometer,and UV-Vis spectrophotometer,be awareness of environmental pollution and prevention,as well as improve the ability of using knowledge to solve practical social problems.Considering compact class hours as well as convenient instruments and low-cost reagents used,this experiment is suitable for promotion in undergraduate experiments of chemistry or other related majors.
