Abstract
An iodine adsorbent comprises an alumina carrier having a large number of pores having a mean pore size of 200 to 2,000 A and silver supported on the alumina carrier. The alumina carrier has a pore volume of at least about 0.1 cc/g. High percent iodine removal is obtained in a highly humid atmosphere, and an amount of silver supported on the carrier is much reduced.
Claims12
An iodine adsorbent which consists essentially of a carrier having a large number of pores having a mean pore size of 200-2,000 A, and an iodine-adsorbing material selected from the group consisting of Ag, Cu, Pb and an iodine-adsorbing salt of Ag, Cu, or Pb, supported on the carrier.
An iodine adsorbent which consists essentially of a carrier having a large number of pores having a mean pore size of 200-2,000 A, and an iodine-absorbing material selected from the group consisting of Ag, Cu, Pb and an iodine-adsorbing salt of Ag, Cu, or Pb supported on said carrier, said carrier consisting of alumina or silica gel and having a pore volume or at least about 0.1 cc/g.
An iodine adsorbent which consists essentially of a carrier having a large number of pores having a mean pore size of 200-2,000 A, and silver or a silver salt supported on the carrier, said carrier supporting the silver or silver salt in an amount corresponding to silver in an amount of 0.1 g/g of the carrier.
