The purpose of this study was to demonstrate magnetic effects on adsorptive properties for the removal of metal ions from waste water. Magnetic adsorbent material in a fixed-bed (column) mode was used for the experiments. A typical experiment involved energizing the magnet to create a field strength of approximately 0.3 Tesla, pumping waste water through the column, and monitoring effluents as a function of time. Magnetic polyamine-epichlorohydrin (MPE) resin was evaluated for plutonium and americium removal; results showed that 325 liters of actinide solution were lowered to 2.77x10{sup -8} g/l plutonium and 7.17x10{sup -10} g/l americium before the plutonium activity in the effluent started to increase. For comparison purpose, the polyamine-epichlorohydrin (PE) resin without magnetite was also evaluated. Minimum concentration observed for plutonium and americium were comparable to the MPE resin; however, breakthrough occurred two orders of magnitude sooner. The results show that the non-magnetic PE resin contributed very little to the adsorption capacity exhibited by the MPE resin, and suggest a synergistic effect between the magnetic field and a porous, magnetic adsorbent material.
