A high-performance liquid chromatography method and a gas chromatography -mass spectrometry method is developed for the determination of phenols in alkaline wastewater from oil refinery. For the same sample, the content of phenol, p-cresol and 0-cresol was 18.49 %, 8.12 % and 1.80 % determined by HPLC, and the content of phenol, p,m-cresol and 0-cresol was 18.40 %, 9.09 % and 1.91 % determined by GC-MS. The results show that the method is precise and accurate. The method is simple and rapid and can be used for the determination of phenols in alkaline wastewater from oil refinery.
