一个研究型化学实验的设计

摘要

设计了一个研究型化学实验,用壳聚糖对模拟废水中的微量重金属离子Cu的吸附进行研究,确定最佳吸附条件。在实验教学过程中引入前沿热点重金属离子的治理,不仅可以让学生掌握更多的实验操作方法,还可以拓展其知识领域。%A research-oriented chemical experiment was designed,investigated the adsorption properties of chitosan for heavy metal ions of Cu.The best condition of absorbing the kind of heavy metal ions had been studied.Introducing the method of deal with heavy metal ion in the waste water in experimental teaching,it will make students know more about operation method,and also be benefit to explore their knowledge areas.
