摘　　要：建立了高效液相色谱法和气相色谱质谱联用法测定炼油碱性污水中的酚类物质含量的两种方法。对同一样品,用高效液相色谱分析其含量,其中苯酚含量为18.49%,对甲酚含量为8.12%,邻甲酚含量为1.80%,用气质联用法测得苯酚含量为18.40%,对、间甲酚含量为9.09%,邻甲酚含量为1.91%。两种方法对三种主要的酚类物质的测定结果相近,都有很好的精密度和准确度。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.
