▎ 摘　　要

NOVELTY - The device has a box housing (1) whose side surface is provided with a flange structure. The flange structure is provided with an impurity gas pumping hole (7) connected with the box housing. The flange structure comprises a concave flange (2) fixed with the side of the box housing and a convex flange (3) connected with the concave flange. A filter membrane is arranged between the concave flange and the convex flange. The box housing is provided with a gas inlet (4) and a xenon outlet (5). USE - Device for purifying gas impurities in xenon based on graphene oxide film. ADVANTAGE - The method enables purifying gas impurity in xenon based on graphene oxide film, which effectively removes the impurity gas mixed in the xenon production process to provide a new technical route for the purification of the gas. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for purifying gas impurities in xenon based on graphene oxide film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for purifying gas impurities in xenon based on graphene oxide film. 1Box housing 2Concave flange 3Convex flange 4Gas inlet 5Xenon outlet 6Container pressure measuring point interface 7Impurity gas pumping port 8Outlet pressure measuring point interface
