Abstract

Polyurethane foam discs (7 mg cm-2 thick) loaded with diethylammonium diethyldithiocarbamate sob traces of mercury, methylmercury and phenylmercury ions quantitatively from aqueous solution. Matrix effects of the loaded polyurethane sorbent on the final measurement are low. Impurities in the foam do not interfere. The procedure is suitable for 0.3-2 μg cm3 mercury with 25-cm3 samples.
