First claim
Opening claim text (preview).
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. 2 . The xenon adsorbent according to claim 1 , comprising at least one selected from the group consisting of lithium, sodium, potassium, magnesium, calcium, strontium, barium, iron, copper, and silver, 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 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. 5 . 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 MWW-type. 6 . The xenon adsorbent according to claim 1 , wherein the xenon adsorbent is a molded body. 7 . The xenon adsorbent according to claim 1 , 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, the absorbance peak has a maximum value in the range of 310 to 330 nm, and the zeolite comprises at least one structure selected from the group consisting of CHA-type, FER-type, HEU-type, and MWW-type. 8 . The xenon adsorbent according to claim 1 , wherein the xenon adsorbent comprises at least one selected from the group consisting of lithium, sodium, potassium, magnesium, calcium, strontium, barium, iron, copper, and silver, 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.
