Abstract

Novel concentration treatment performance of radioactive iodine from radioactive waste is examined using the paper membrane, in which trimethylhydroxypropylammonium groups were homogeneously dispersed. The ion-exchange capacity of the paper membrane increased compared to that of normal anion exchange paper membrane by 30%. Ion transport across the paper membrane is evaluated with electroconductive membrane permeability derived from transmembrane potential and membrane conductance, and diffusional membrane permeability derived from transmembrane potential and ion flux in Na125I or NaCl single electrolyte concentration-cell system. In addition, the influence of glucose and urea, on the iodide ion across an anion exchange paper membrane were investigated in the Na125I concentration-cell system. The novel prepared paper membrane exhibits the high anion selective permeation through the paper membrane and indicates radioactive iodine permselectivity due to electrostatic effect.
