| 摘要 |
<p>The invention relates to a method for decontaminating solid iodine filters containing silver iodide and/or physisorbed molecular iodine. Said method consists in bringing the filter into contact with an aqueous solution of a reducing agent chosen from hydroxylamine, hydroxylamine salts, ascorbic acid, ascorbic acid salts, ascorbyl esters, sodium borohydride salts, sodium hypophosphite, formaldehyde, urea, formic acid and the mixtures thereof, in order to extract iodine from the filter and to solubilize it in the aqueous solution. Silver can also be dissolved in the reducing agent solution or in an other appropriate aqueous solution either simultaneously or successively.</p> |
