高效液相色谱法测定环境水中的酚类化合物

Determination of Phenols in Environmental Water by Solid Phase Extraction and High Performance Liquid Chromatography

  • 摘要: 目的建立固相萃取-高效液相色谱测定环境水样中酚类化合物的分析方法。方法研究13种酚类化合物在C18柱上的色谱行为,优化固相萃取条件和HPLC分离和测定条件,对其中10种酚进行定量分析。结果待测物的线性范围为:0.1~5μg/L;相关系数0.999以上;方法的日内和日间相对标准偏差分别为1.1%~4.2%和3.9%~13.7%.检出限为0.01~0.04μg/L.用该方法对生活污水、医院污水、江水、河水进行测定,样品中酚类化合物的加标回收率范围为80.0%~114.3%;样品测定结果相对标准偏差在0.6%~9.9%范围内,符合卫生检验的要求。结论本方法简便、准确、灵敏度高,对水样中酚类化合物的检测具有实用价值。

     

    Abstract: ObjectiveA high performance liquid chromatography(HPLC)with a solid phase extraction for the determination of thirteen phenols in environmental water was developed.MethodsThirteen phenols were investigated.Ten phenols was quantitatively determined by HPLC.ResultsThe linear ranges were from 0.1 to 5μg/L(r=0.999-0.999 9);The within-day RSD and between-day RSD were 1.1%-4.2% and 3.9%-13.7% respectively.The detection limits were from 0.01μg/L to 0.04μg/L.Five samples of environmental water were determined by this method.The recoveries ranged from 80.0% to 114.3%.RSD was 0.6%-9.9%,which was up to the demand of hygiene inspection.ConclusionIt was concluded that cis method was simple,accurate with high reproducibility.It had practical value for determination of phenols in environmental water.
