Abstract
Abstract Potassium glycolate was used as the dechlorinating agent in the development of a screening technique for the determination of PCBs in waste oils. Due to the high extraction efficiency of polyethylene glycols in terms of removing PCBs from mineral oil, the analytical samples were directly applied to the dechlorination-reaction mixture. The samples were then analyzed for chloride using a flow-injection analysis system with a thin-layer amperometric detector employing a silver working electrode. This system demonstrated a low detection limit for chloride of 100 ng (at S/N = 3) and a 3% precision. The detection limit of the dechlorination reaction — chloride analysis system was limited by the detection limit of the latter. This corresponds to a detection limit of 0.9 mg/kg for Aroclor 1260. This detection limit is well below the regulatory limit of 50 mg/kg which defines whether a waste oil is contaminated with PCBs.
