摘　　要：对经典的荧光分析法实验“饮料中硫酸奎宁含量的测定”进行了拓展,将简易荧光光度计搭建及应用拓展的实验模块引入了常规的实验教学。通过优化和改进荧光光度计的搭建方法,使其能够更好地应用于实验体系。教学实践结果表明,这种教学模式丰富了荧光分析法实验内容,有助于提高学生的实验兴趣,进一步强化学生综合实际动手能力培养。“Determination of Quinine sulphate content in tonic water”is a classical fluorescence experiment.This paper expands the experimental content by introducing the constructed fluorimeter into first-year undergraduate teaching practice.Here,a simple fluorimeter is developed and applied into the experiment.The practice shows that this teaching design can enrich the teaching content,inspire students’interest and improve their comprehensive ability.
