Abstract:

An experiment was designed for determination of metal ions in the leaching solution of thermos cups by inductively coupled plasma atomic emission spectrometry (ICP-AES), which can greatly stimulate the students' interest. This experiment can not only guide students to apply their knowledge and conduct in-depth research, but also improve their laboratory skill and cultivate the spirit of teamwork. This experiment is suitable for undergraduate laboratory teaching, because the content and process of this experiment are complete, the experimental reagents and process are safe and green, the experimental sample processing is quick and easy, and the experimental time is reasonable.

Key words: ICP-AES, Laboratory teaching reform, Instrumental analysis laboratory teaching
