Abstract:

The amount of reagent used in the process of analytical chemistry experiment is large, resulting in more waste liquid, which will cause great pollution to the environment and affect the health of teachers and students. Therefore, the greening of analytical chemistry experiment and the greening treatment of waste liquid are of great significance. Taking the basic experiment of analytical chemistry course in the National Demonstration Center for Experimental Chemistry and Chemical Engineering Education at Hunan Normal University as an example, the green reforms on the analytical experimental projects are carried out by means of miniaturization and resource reuse.

Key words: Analytical chemistry experiment, Greening, Resource reuse
