Abstract
To avoid using toxic solvents, weak basic anion exchange resin with aromatic amine groups was prepared by grafting 4-vinyl pyridine onto polystyrene microspheres through simultaneous radiation grafting method. In batch adsorption experiments toward Re(VII) which was selected to simulate 99Tc, the adsorption efficiency maximized when the concentration of HNO3 was set at 0.02 M. Using reductive eluents SnCl2 it was found a method to efficiently regenerated resin at low acidity. For adsorption toward 99Tc, the results matched well with Re, which indicates that the prepared exchangers will have wide applications in the future to remove 99Tc from spent nuclear fuel.
