Abstract:

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.

Key words: Analytical chemistry experiment, Persulfate, Activation
