Abstract:A new analytical method for the determination of naproxen, ketoprofen, diclofenac, carbamazepine, and triclosan in water samples by liquid chromatography is developed and validated. The method is based on the extraction of the analytes by a polydimethylsiloxane (PDMS) rod. The different parameters affecting extraction, such as the addition of salt, pH, initial volume, extraction and elution times and elution solvent, as well as the application of sonication, are studied. The results showed that the detection l… Show more
