Abstract : The problem of pollution control by trace heavy metal ions e.g. bismuth, phenols and chlorophenols etc in water has become one of the modern man’s preoccupations. Thus, the work presented in this study can be summarized as follows: 1. Studying the retention characteristics of bismuth(III) from aqueous iodide solution by polyurethane foam treated with 1, 10 phenanthroline as low cost and effective solid phase extractor (SPE) in batch mode of separation. 2. The kinetics and sorption isotherm models of the retention step were determined and are properly assigned. Moreover, the thermodynamic parameters (ΔH, ΔS, ΔG) of the retention step were also determined and revealed to the extothermic and spontaneous nature of the retention step. 3. Chromatographic separation of [BiI4]- from aqueous media by reagent treated PUFs packed column was successfully achieved. Complete recovery of the retained bismuth species was recovered easily with nitric acid. 4. Application of static mode of separation for studying the retention profile, kinetics and thermodynamic characteristics of some phenol and other chlorophenol from aqueous solution by polyurethane physically immobilized nanosized magnetic iron oxide (Fe3O4). Excellent retention was achieved in acidic solution of pH <1.0. 5. Polyurethane foams treated nanosized Fe3O4 packed column was used as a low cost and effective solid resilient sorbent for retention of phenols from aqueous media of pH <1.0. The results complete extraction, separation and recovery of the tested phenols from water at 5-10 mL/min.
