ʻO ka loiloi in-situ o nā huahana paʻa ʻole a me ka nānā ʻana i nā spectral pūnaewele i lilo i mau ala noiʻi wale nō
I kekahi hopena nitrition, pono e hoʻohana ʻia nā ʻakika ikaika e like me ka nitric acid e hoʻohana i nā mea maka no ka hana ʻana i nā huahana nitric.ʻAʻole paʻa a maʻalahi ka hoʻoheheʻe ʻana o ka huahana nitratation o kēia pane.No ka loaʻa ʻana o ka huahana i manaʻo ʻia, pono e hoʻokō ʻia ka hopena holoʻokoʻa i kahi kaiapuni o -60 ° C.Inā hoʻohana ʻia nā ʻenehana keʻena hana waho e like me ka chromatography, mass spectrometry, a me ka nuclear magnetic resonance no ka nānā ʻana i ka huahana, hiki ke hoʻoheheʻe ʻia ka huahana i ka wā o ke kaʻina loiloi a ʻaʻole hiki ke loaʻa ka ʻike pololei e pili ana i ka hopena.Ke hoʻohana nei i ka ʻenehana spectroscopy pūnaewele no ka nānā ʻana i ka manawa maoli, ʻike ʻia ka hoʻololi ʻana o ka huahana a me ka holomua o ka pane.Ma ke aʻo ʻana o ia mau hopena i loaʻa nā ʻāpana paʻa ʻole, ʻo ka ʻenehana nānā pūnaewele ʻo ia wale nō ka ʻenehana noiʻi kūpono.
Hoʻopaʻa ke kiʻi ma luna nei i ka nānā ʻana ma ka pūnaewele i ka manawa maoli o ka hopena nitrification.ʻO nā hiʻohiʻona hiʻohiʻona o ka huahana ma nā kūlana 954 a me 1076 cm-1hōʻike i kahi kaʻina hana o ka hoʻonui a me ka emi ʻana i ka manawa, e hōʻike ana i ka lōʻihi o ka manawa pane e alakaʻi i ka decomposition o nā huahana nitratation.Ma ka ʻaoʻao ʻē aʻe, ʻo ka ʻāpana kiʻekiʻe o ka piko hiʻohiʻona e hōʻike ana i ka ʻike huahana i loko o ka ʻōnaehana.Mai ka ʻikepili nānā pūnaewele, hiki ke ʻike ʻia ʻo ka ʻike huahana ka mea kiʻekiʻe loa ke hele ka hopena i 40 mau minuke, e manaʻo ana ʻo 40 mau minuke ka hopena hopena maikaʻi loa.
