| Abstract: | An HPLC method is established to determine phenol and its degradation intermediates （catechol, resorcinol, quinone） in this paper. An optimum condition is found. The column temperature is 25℃. Methanol-water（50：50） as the mobile phase at a flow rate of 0.5 ml/min is applied. The linearity range is 2-10mg/L. The external standard method is used, the RSD range and the recovery rate range are 0.4%--1.6% and 95.3%--101.6%, respectively. The detection limits range from 0.0735 to 0.1298 mg/L. The results show that this method is simple, rapid, accurate, highly active and can be used for the separation and determination of phenol and its catabolites. |
