Abstract Folic acid was found to enhance the chemiluminescence from NaIO4-H2O2 system. The chemiluminescent intensity was linear with the concentration of folic acid, based on which, a chemiluminescent method has been established for folic acid determination. The experimental phenomenon has been designed as a new experiment teaching case of “chemiluminescent analysis”. The experimental conditions of the system have been optimized to explore the experimental conditions suitable for teaching. In the process of teaching, we should guide students to observe the phenomenon of folic acid enhanced-chemiluminescence and investigate the mechanism. Students' ability to use theoretical knowledge would be exercised, and students' scientific research abilities and innovation consciousnesses would be cultivated.
