ʻAno hana hou e hoʻohana pono ai i ka ikehu no ka unuhi ʻana i nā kinoea inert mai ka lewa

Nā kinoea hanohanokriptoa me nxenonaia ma ka ʻaoʻao ʻākau loa o ka papa periodic a he mau hoʻohana pono a koʻikoʻi hoʻi. Eia kekahi laʻana, hoʻohana ʻia nā mea ʻelua no ke kukui ʻana.Xenonʻo ia ka mea ʻoi aku ka pono o nā mea ʻelua, nona nā hoʻohana hou aku i ka lāʻau lapaʻau a me ka ʻenehana nukelea.
ʻAʻole e like me ke kinoea kūlohelohe, ka mea i nui ma lalo o ka honua,kriptona mexenonhe hapa liʻiliʻi wale nō o ka lewa o ka honua. No ka hōʻiliʻili ʻana iā lākou, pono nā kinoea e hele i kekahi mau pōʻaiapuni o kahi kaʻina hana ikaika i kapa ʻia ʻo cryogenic distillation, kahi e hopu ʻia ai ka ea a hoʻomaʻalili ʻia a hiki i kahi o -300 degere Fahrenheit. Hoʻokaʻawale kēia hoʻomaʻalili nui i nā kinoea e like me ko lākou kiko paila.
He mea houkriptona mexenonhe mea makemake nui ʻia ka ʻenehana hōʻiliʻili e mālama ai i ka ikehu a me ke kālā. Manaʻoʻiʻo nā kānaka noiʻi ua loaʻa iā lākou ia ʻano hana, a ua hōʻike kikoʻī ʻia kā lākou hana ma ka Journal of the American Chemical Society.
Ua hana ka hui i ka silicoaluminophosphate (SAPO), he kristal i loaʻa nā pores liʻiliʻi loa. I kekahi manawa aia ka nui o ka pore ma waena o ka nui o kahi ʻātoma krypton a me kahixenonʻātoma. Liʻiliʻikriptonhiki i nā ʻātoma ke hele maʻalahi ma waena o nā pores ʻoiai e paʻa ana nā ʻātoma xenon nui. No laila, hana ʻo SAPO e like me kahi kānana molekala. (E nānā i ke kiʻi.)
Ma ka hoʻohana ʻana i kā lākou mea hana hou, ua hōʻike nā mea kākau i kēlākriptonhoʻolaha i 45 mau manawa ʻoi aku ka wikiwiki ma mua oxenon, e hōʻike ana i kona pono i ka hoʻokaʻawale ʻana i ke kinoea hanohano ma ka mahana o ka lumi. Ua hōʻike nā hoʻokolohua hou aʻe ʻaʻole wale ka hakakā ʻana o ka xenon e ʻomi ma o kēia mau pores liʻiliʻi, akā ua maʻa mau hoʻi ia e hoʻopili ma luna o nā kristal SAPO.
Ma kahi ninaninau me ACSH, ua ʻōlelo nā mea kākau ua hōʻike kā lākou loiloi mua e hiki i kā lākou hana ke hōʻemi i ka ikehu e pono ai e hōʻiliʻilikriptona me ka xenon ma kahi o 30 pakeneka. Inā he ʻoiaʻiʻo kēia, a laila e nui nā mea e haʻaheo ai nā kānaka ʻepekema ʻoihana a me nā poʻe hoihoi i ke kukui fluorescent.
