<p><P>PROBLEM TO BE SOLVED: To efficiently recover xenon from used equipment in which xenon is sealed, and to prevent a worker who disassembles and sorts the equipment from inhaling xenon. <P>SOLUTION: Xenon is recovered with a gas adsorption device 1 comprising copper-exchanged ZSM-5 zeolite 3 having a pore diameter of 4.5-7.3Å, and a container 2 made of a hardly gas-permeable material in which the copper-exchanged ZSM-5 zeolite 3 is stored. The container 2 has a joining part 4 which forms a communicating passage between the space in which the copper-exchanged ZSM-5 zeolite 3 is stored and a xenon-sealed space in equipment in which xenon is sealed so as to attach the gas adsorption device 1 to the equipment, and an arbitrarily openable mechanism made of low-melting glass 5, which obstructs the communicating passage until a predetermined operation is performed and which, when the predetermined operation is performed, allows the space in which the copper-exchanged ZSM-5 zeolite 3 is stored to communicate with the xenon-sealed space in the equipment. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
