Abstract
Official abstract text for this publication.
A xenon adsorbent capable of efficiently adsorbing xenon, even at a low concentration, from a mixture gas is Provided.A xenon adsorbent comprising a zeolite having a pore size in the range of 3.5 to 5 Å and a silica alumina molar ratio in the range of 10 to 30.
First claim
Opening claim text (preview).
The invention claimed is: 1. A xenon adsorbent comprising: a zeolite having a pore size in the range of 3.5 to 5 Å; and a silica alumina molar ratio in the range of 10 to 30, wherein the xenon adsorbent comprises silver, an ultraviolet-visible absorption spectrum of the silver measured after calcination of the xenon adsorbent at 500° C. in air has an absorbance peak in the range of 290 to 350 nm, and the absorbance peak has a maximum value in the range of 310 to 330 nm. 2. The xenon adsorbent according to claim 1 , further comprising at least one selected from the group consisting of lithium, sodium, potassium, magnesium, calcium, strontium, barium, iron, and copper, as a metal component contained in the zeolite. 3. The xenon adsorbent according to according to claim 1 , wherein the stoichiometric ratio of the metal component relative to the aluminum in the zeolite is 0.1 to 1.0 equivalent amount (in a case where a valence of an ion of a metal is represented by n, the equivalent amount is a value obtained by multiplying a metal/Al molar ratio by the valence n of the metal). 4. The xenon adsorbent according to claim 1 , wherein the zeolite comprises at least one structure selected from the group consisting of CHA-type, FER-type, HEU-type, and MW-type. 5. The xenon adsorbent according to claim 1 , wherein the xenon adsorbent is a molded body. 6. The xenon adsorbent according to claim 1 , wherein the xenon adsorbent further comprises at least one selected from the group consisting of lithium, sodium, potassium, magnesium, calcium, strontium, barium, iron, and copper, as a metal component contained in the zeolite, and the zeolite comprises at least one structure selected from the group consisting of CHA-type, FER-type, HEU-type, and MWW-type.
