| Abstract: | Derivative ratio derivative ultraviolet spectrophotometry is simple to operate in the simultaneous determination of benzoyl peroxide and benzoic acid in flour. The recovery rate and accuracy of the determination high, the concentration range of them were 0 - 13mg/L and 0 - 9mg/L respectively, it accorded with the linear correlations, the regression correlative coefficient r was above 0.999. This method was reliable and accurate. |
