The feasibility of using TBP-loaded polyurethane foams as column fillings in reversed-phase chromatography was examined and their capacities were determined. Separation of nickel, bismuth, and palladium was achieved. The effect of flow-rate, temperature and ratio of the separated ions on the efficiency of separation was tested. Elution with high flow-rate affected the efficiency of the column at 25° but not at higher temperature (e.g. 35°). Once the column was prepared, it could be used several times without affecting its efficiency.
