Abstract
SPE (solid-phase extraction) and LC/MS (liquid chromatography/mass spectrometry) method has been developed for the analysis of thirty three pharmaceuticals in aqueous sample, such as sewage and river water. The effects of disk type and pH on the extraction of pharmaceuticals in water were examined. Hydrophilic DVB disk was more efficient than otadecyl (C18) disk and the extraction efficiency of pharmaceuticals at pH=2 (53-139%) was better than that at pH=5. Thirty three pharmaceutics in sewage influent, effluent and river sample were analyzed using the method developed in this study. Fourteen drugs (acetaminophen, acetylsalicylic acid, diclofenac-Na, ibuprofen, ketoprofen, mefenamic acid, naproxen, carbamazepine, clofibric acid, gemfibrozil, caffeine, erythromycin-H₂O, lincomycin, and amoxicillin) were detected and the levels of detection were 0.001~10.1 ppb (μg/L).
Key Words: pharmacueticals, sewage treatment plants (STPs), Liquid Chromatography/Mass Spectrometry (LC/MS), Solid Phase Extraction (SPE)
