【Abstract】 Objective To study the methods for determination of semi volatile organic compounds in river water.Methods A combination of liquid liquid extraction, K D concentrator, gas chromatograph (GC) and mass spectrometry was used to determine semi volatile organic compounds in river water.Results It was found that it was more efficient to concentrate semi volatile organic compounds in river water by liquid liquid extraction. Then it was analyzed by GC/MS. This systemic method is very stable and meets specific QC acceptance criteria with high accuracy and repeatability.Conclusion It was found that it was more efficient to concentrate semi volatile organic compounds in river water by liquid liquid extraction. Then it was analyzed by GC/MS. This systemic method is very stable and meets specific QC acceptance criteria with high accuracy and repeatability.更多还原
