A pulsating column technique based on the resilience of open-cell polyurethane foam is described. After loading with a suitable hydrophobic organic reagent, a foam cylinder is packed in a conventional medical syringe (pulsating column) and made to pulsate in the solution containing the species to be separated. Based on theoretical considerations, two experimental arrangements for a new separation and pre-concentration method have been developed. The value of the method is demonstrated by the separation of 131I and 203Hg from large volumes of aqueous solutions.
