Silver-exchanged adsorbent material useful for scavenging radioactive iodine from gaseous iodine compounds

摘要

The present invention relates to a silver-exchanged adsorbent material comprising a zeolite, said zeolite comprising between 1 and 6% silver by weight relative to the total weight of the zeolite exchanged for silver and capable of being subjected to a pretreatment thermal before its exchange for money. The present invention also relates to the use of the adsorbent material according to the first object of the invention to trap the radioactive iodine of iodine compounds in gaseous form as well as the process for preparing said adsorbent material.
