Iodine adsorbers in nuclear power plants

Iodine adsorber
Reactor safety: Radioactive gaseous iodine is one of the most important radionuclides whose release from nuclear facilities must be prevented. For the selective removal of iodine in exhaust gas treatment systems of nuclear power plants, reprocessing plants, and nuclear research facilities, C&CS offers the following three iodine adsorbents as proven solutions from CLARIANT:

C&CS offers the following CLARIANT types of iodine adsorbers:

IODINE ADSORBENT AC6120 / 7%(Ag)
IODINE ADSORBENT AC6120 / 12% (Ag)
IODINE ADSORBENT DSM11

The two silver-containing iodine adsorbents AC6120 / 7% and AC6120 / 12% were developed for the selective adsorption of organically bound iodine (e.g. methyl iodide or iodomethane) and inorganic iodine.

DSM11, containing potassium iodide, was developed for the selective absorption of inorganic iodine in the presence of organically bound iodine. For complete absorption of both inorganically and organically bound iodine, it is used in combination with AC6120.

Due to the characteristic chemical properties of iodine with silver compounds and potassium iodide, iodine absorption in the three adsorbents occurs via chemisorption. Noble gases are not adsorbed due to their specific chemical composition.
