| Abstract: | A method for the simultaneous determination of benzole acid and salicylic acid in mixtures in 1. 0 mol/L aqueous H2SO4 solution by derivation synchronous fluorimetry was proposed. The detection limits of benzoic acid and salicylic acid are: 0. 026 and 0. 038 Hg/mL, respectively. The relative standard deviation is 1. 8% and 3.1%, respectively. This method has been successfully used to determine benzoic acid and salicylic acid in commercial preservative and bactericide simultaneously. |
