Ultrasonic-assisted micellar extraction coupled with high-pressure liquid chromatography has been developed for the determination of pentachlorophenol (PCP) in paper packaging materials. A nonionic surfactant, polyethylene glycol sorbitan monolaurate (Tween 20), was used for ultrasonic extraction and the method was applied to different paper packaging materials under optimized conditions. The recoveries for spiked samples were 83-90.1% and relative standard deviations were <5.0%. The limit of detection and the limit of quantification for PCP were 0.9 and 2.0 mu g/g, respectively. Results confirmed that this relatively simple procedure proved satisfactory for the determination of PCP in paper packaging materials.
