Abstract: ⁹⁹Tc is one of the fission products from nuclear power plant, it is a long-lived radio nuclide with a relatively high fission yield. The separation of technetium from high level liquid waste (HLLW) plays an important role in the nuclear waste reprocessing. In this article, rhenium was selected as the simulating nuclide of technetium. The adsorption and elution behavior of rhenium(Ⅶ) with a porous silica-based anion exchanger AR-01 resin were investigated. The influence of temperature, acid concentration and the equilibrium time on the adsorption were studied. Reductive elution was also studied. The results show that the adsorption is exothermic with fast kinetics, increasing the acid concentration will reduce the adsorption. The dynamic adsorption capacity at flow rate of 1.0 mL/min is 105 mg/g. The addition of SnCl₂ to elute solution can improve the efficiency of elution significantly. The resin also has satisfying regeneration property. The research offers reference to study the application of AR-01 resin for the separation of technetium from HLLW.
