| titleOfInvention | How to regenerate a solid iodine filter |
| abstract | The present invention relates to a method for regenerating a solid filter comprising iodine in the form of silver iodate and / or silver iodide and optionally physisorbed molecular iodine in a solid filter comprising silver in the form of nitrate. The method includes the following steps. a) contacting the filter with a basic aqueous solution containing a reducing agent, followed by separating the filter from the basic aqueous solution to extract iodine contained in the filter, said extraction at ambient temperature To be implemented, b) extracting the silver contained in the filter obtained in step a) by contacting the filter with an aqueous acid solution and subsequently separating the filter from the aqueous acid solution; and c) the filter with a silver nitrate solution. Impregnating the filter obtained in step b) with silver by contacting and subsequently drying the filter. The invention can be used in the following areas: nuclear facilities, in particular spent nuclear fuel reprocessing plants. |
