Alternative
A method for the determination of polychlorinated biphenyls in paper and cardboard
Abstract
After an extraction of the samples with ethanolic potash lye, the solution is cleaned and enriched through solid/liquid extraction (reverse phase). PCB are separated by means of a high-resolution quartz capillary column through gas chromatography and determined with an ECD detector. Seven individual components are covered that can be considered representative. The total amount of their concentration is at least 20% of the overall concentration of PCB in paper, cardboard or pasteboard.
