Description
Summary:In continuation of their research (see WRC Information, 1978, 5, No.1, Abstr. No.25) the authors have used flexible polyurethane foam plugs to concentrate trace amounts of six polynuclear aromatic hydrocarbons from large volumes of treated and raw waters. Retention efficiencies were at least 88 per cent from treated and 72 per cent from raw water, and the concentrate was purified by solvent partitioning and column chromatography. Thin-layer chromatography with fluorometric detection was more sensitive and selective than gas-liquid chromatography/flame ionization.
