摘要
离子色谱法作为一种相对独立的色谱方法已被引入本科生实验教学,该文应用离子色谱仪分析了3种不同水体中的常见阴离子,包括管道雨水、地表径流和校内景观池塘水。为激发学生的学习兴趣,采用了对照仪器结构来讲解实验原理的方式,将理论与实际相结合;鼓励学生参与水样采集;进行分组操作实验;共享实验数据。在仪器运行期间利用课内思考题的方式,促使学生认真观察离子色谱仪的结构设计、理清样品分析过程,并完成思考题,极大地调动了学生的主观能动性,取得了很好的教学效果。
As a relatively independent chromatography method,ion chromatography has been introduced into undergraduate experimental teaching.In this experimental teaching design,ion chromatography was applied to analyze common anions in three different water bodies,including rainwater collected in pipeline,surface runoff and pond water in the campus.In order to stimulate students’interest in learning,several teaching methods were applied.The experimental principle was explained according to the structure of the instrument,which combined theory with practice.The students were encouraged to participate in water sample collection and were divided into several small groups to operate the instrument during the experiment.The experimental data were shared for adequate analysis.During the operation of the instrument,the students were required to answer several questions by carefully observing the structure of the ion chromatograph and the process of sample analysis,which greatly motivated their initiative.This experimental achieved good teaching results.
