自主设计型实验是我校分析化学实验教学体系的重要环节之一。本文以分析化学实验教学过程中产生的含铬废水为处理对象。要求学生通过自主查阅文献、设计实验方案、分析实验方案的可行性，再进行实验探究，并对实验结果进行综合分析。该教学过程的实施，不仅培养了学生分析和解决复杂问题能力，而且培养了他们的创新思维意识。
- Wastewater containing chromium ion,
- Self-design experiment,
- Feasibility analysis,
- Potassium dichromate crystal,
- Comprehensive experimental ability,
- Open laboratory teaching
