Abstract

Abstract:

Objective: To develop a new flow injection chemiluminescence method for determining benzoyl peroxide in flour. Methods: KI can be oxidized by benzoyl peroxide to produce I2. This reaction is coupled with a luminal-H2O2 chemiluminescence system to determine benzoyl peroxide in flour. Results: The determination range of this method is 3.0 × 10-8－4.0 × 10-6 g/mL, and the detection limit of this method is 4.0 × 10-9 g/mL with a relative standard deviation of 2.2%. Conclusion: This method is characteristics of simple, high selectivity, accuracy and sensitivity.

Key words: flow injection, chemiluminescence, benzoyl peroxide
