Removal of 125I from radioactive experimental waste with an anion exchange paper membrane.
The behavior of radioactive iodide and chloride ions through an anion exchange paper membrane to remove 125I from radioactive experimental waste has been studied with nonequilibrium thermodynamic analyses. Anion exchange paper membrane was found to be electroconductively more permeable to iodide ion than to chloride ion. The iodide ion bound more strongly to the anion exchange site within a membrane phase than the chloride ion by more than twice. The results suggested that an anion exchange paper membrane was appropriate for the filtration removal system.
