Abstract

Earlier work (1) reported investigations on 21 inorganic materials suggested for technetium (99-Tc), sulphur (35-S), iodine (125-I) isotope removal from simulated aqueous nuclear wastes by anion exchange. This work has been extended to a systematic study of five of the most promising of the original anion exchangers. These materials are lead sulphide, -mercarbide and the oxides of zirconium (Zirox), iron (Ferrox) and aluminium. The work presented here details anion kinetics and equilibria and leach tests of exchanger/cement composites. The ion pairs studied were N03/TcO4, NO3 -/SO4 2-, NO3 -/I-. The perrhenate ion was used as carrier for 99-TcO4 -.
