Implementing Water Analysis Using Ion Chromatography into Early Undergraduate Chemistry Laboratory Curricula and Outreach Education

化学(12)我们使用两个离子色谱(IC)系统，在大学一年级和二年级的水分析中引入基于探究和发现的实验项目，并通过扩展到有天赋的中学生。通过离子色谱准确分析各种水样中的阳离子和阴离子，改善了学生的实验室经验，因为它超过了难以控制、详尽和繁琐的传统滴定方法。通过将动机和学习与传统实验的结果进行比较，评估新模块对实验室课程的影响。

Chemistry (12) We employ two ion chromatography (IC) systems to introduce inquiry and discovery-based experimental projects in water analysis at both the college freshman and sophomore levels, as well as through outreach to gifted middle school students. Accurate analysis of cations and anions by ion chromatography in various water samples improves the laboratory experience of students, since it surpasses conventional titration methods that are difficult to control, exhaustive and tedious. The impact of the new modules on the laboratory curricula is evaluated by comparing motivation and learning with results from traditional experiments.
