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

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.
