In the experiment of extracting benzoic acid from kerosene with tap water as the extractant, the concentration of benzoic acid is usually determined by volumetric titration. The error of this method is large and the material balance is poor. In this paper, a high performance liquid chromatography (HPLC) was used to separate benzoic acid and kerosene with methanol as a mobile phase. The quantitative analysis was made by using UV-Vis detector. Compared with the titration analysis, the accuracy of HPLC was higher and the recovery rate of material balance was up to 95%.
- Liquid-liquid extraction,
- High performance liquid chromatography,
- Material balance
