| description | In this study, a wavelength-shift-based colorimetric sensing approach for the peroxide number of milk powder using CsPbBr<sub>3</sub> perovskite nanocrystals (CsPbBr<sub>3</sub> NCs) has been developed. Through the fat extraction, REDOX reactions and halogen exchange, as well as the optimized experimental conditions, a colorimetric sensing method was established to determine the peroxide number of milk powder samples. The integrated process of milk powder fat extraction and the REDOX process greatly shortened the determination time. This colorimetric method has a good linear correlation in the range of the peroxide number from 0.02 to 1.96 mmol/kg, and the detection limit was found to be 3 μmol/kg. This study further deepens the application prospect of wavelength-shift-based colorimetric sensing using CsPbBr<sub>3</sub> NCs. |
