Iodine adsorbent
An iodine adsorbent comprises a carrier, a film of iodine-adsorbing material or compound deposited on the surface of the carrier, and a layer of organic material coated on the surface of the film, and has a high iodine removal efficiency at a high humidity.
What is claimed is:
1. An iodine adsorbent which comprises:
a carrier;
a film of iodine-adsorbent material deposited on the surface of the carrier; and
a liquid layer of organic material selected from the group consisting of dioctyl phthalate, dioctyl sebate, or silicone oil, coated on the surface of the film, said layer comprising a hydrophobic organic material that is a better solvent for iodine than water.
2. An iodine adsorbent which comprises:
a carrier;
a film of iodine-adsorbent material selected from the group consisting of silver sulfate or silver sulfite deposited on the surface of the carrier; and
a liquid layer of organic material coated on the surface of the film, said layer comprising a hydrophobic organic material that is a better solvent for iodine than water.
3. An iodine adsorbent according to claim 1 or 2, wherein the carrier is porous.
4. An iodine adsorbent which comprises:
a porous carrier;
a film of iodine-adsorbent material deposited on the surface of the carrier; and
a liquid layer of organic material coated on the surface of the film, the volume of the organic material forming said layer being 0.2-0.8 times the pore volume of the carrier, said layer comprising a hydrophobic organic material that is a better solvent for iodine than water.
