During the outbreak of novel coronavirus pneumonia, 84 Disinfectant has been widely used. It is very important to determine the available chlorine content in 84 Disinfectant. A new method to rapidly determine the available chlorine content in 84 Disinfectant by automatic potentiometric titration was established. Statistically, there is no significant difference in results between automatic potentiometric titration and manual titration. Combined the principles of analytical chemistry and the application to the determination of anti-epidemic material, this experiment has theoretical and practical significance, and can be used as an experiment in analytical chemistry laboratory for sophomore students.

Key words: Automatic potentiometric titration, Rapid determination, 84 Disinfectant, Available chlorine content
