摘要
设计了活化过硫酸盐降解模拟染料废水的实验,通过直观的实验现象和过硫酸钠不同活化方式的应用,发挥学生学习的主动性,引导学生查阅相关文献,对实验进行开放式设计及探索。针对不同层次学生采取分层次引导,循序渐进地培养学生的动手能力、解决实际问题的能力和创新能力。
An exploratory analytical chemistry experiment“decolorization of dye by persulfate activation”,has been designed,and the students’initiative to participate actively have been stimulated through obvious experimental phenomena and application of different analytical methods.Students are led to consult the relevant reference to design the open experimental plan and exploration.In addition,different teaching plans were adopted for different levels of students,and students’laboratory skills,ability to solve practice problem and capacity to innovate was cultivated step by step.
