METHOD FOR REGENERATING A SOLID IODE FILTER |
| abstract |
The invention relates to a method for regenerating a solid filter containing iodine in the form of iodide and / or silver iodate and optionally physisorbed molecular iodine in a solid filter containing silver. in the form of nitrate. This process comprises the following steps: a) extracting from the filter the iodine it contains by bringing this filter into contact with a basic aqueous solution containing a reducing agent, this extraction being carried out at room temperature, and then separating the filter from this basic aqueous solution; b) extracting from the filter obtained in step a) the silver contained therein by contacting this filter with an acidic aqueous solution, and then separating the filter from this acidic aqueous solution; and c) impregnating the filter obtained in step b) with silver by contacting this filter with a solution of silver nitrate, and then drying the filter. Field of application: nuclear facilities, including used nuclear fuel reprocessing plants. |
