摘　　要：为更好地贯彻四川大学关于建设一批综合性、设计型实验课程和创新探索(创业)型实验课程的教学改革指导方针,该文设计了一个绿色分析化学实验,利用从茶叶中提取的茶多酚作为显色剂,实现在溶液和固相纸基质两种情况下对实际样品中铁含量的检测。该实验综合性强,绿色无污染,操作简便,响应快速直观,可作为综合性的创新创意实验面向学生开放。In order to better carry out the teaching reform guidelines of Sichuan University on the construction of a number of comprehensive,design-typed experimental courses and innovative exploration(entrepreneurial)experimental courses,a green analytical chemistry experiment is designed,with polyphenols extracted from tea leaf as the chromogenic reagent,to determine the iron content of real sample both in solution and on the filter paper substrate.This experiment is comprehensive,green,easy to handle,fast-responding and visual,therefore,this experiment could be served as a comprehensive innovative chemical experiment open to students.
