ʻakika manawa(HIO ₄) he ʻakika ikaika anorganic koʻikoʻi i loaʻa ka laulā o nā noi ma ke ʻano he oxidant ma nā ʻano ʻepekema a me nā ʻoihana ʻenehana. E hāʻawi kēia ʻatikala i kahi wehewehe kikoʻī i nā hiʻohiʻona o kēia hui kūikawā a me kāna mau noi koʻikoʻi ma nā ʻano āpau.
Nā waiwai kemika o ka waika manawa
ʻO ka periodate ke kūlana hoʻokahe kiʻekiʻe loa o ka ʻakika i loaʻa i ka oxygen o iodine (+7 valence), maʻamau i loaʻa i nā kristal kala ʻole a i ʻole ka pauka keʻokeʻo. Loaʻa iā ia nā hiʻohiʻona nui:
Ka ikaika oxidizing hiki:Me ka hiki ke hōʻemi maʻamau a hiki i ka 1.6V, hiki iā ia ke hoʻoheheʻe i nā ʻano mea like ʻole a me nā mea hoʻohuihui ʻole.
Hoʻoheheʻe wai:Hiki ke hoʻoheheʻe ʻia i loko o ka wai, e hana ana i kahi hopena kala ʻole
Hiki ʻole ka wela:e decompose ke hoʻomehana ʻia ma luna o 100 ° C
ʻakika:no ka waika ikaika, hemo loa i ka wai
Nā wahi noi nui
1. Nā noi ma ke Kemika Analytical
(1) Ka hopena o Malaprade
ʻO ka hoʻohana kaulana loa o ka waika periodic ma ka loiloi kemika o nā carbohydrates. Hiki iā ia ke hoʻoheheʻe a wāwahi i nā hale diol e pili ana (e like me nā cis diols i loko o nā molekele carbohydrate) e hana i nā aldehydes a i ʻole nā ketones. Hoʻohana nui ʻia kēia pane no:
-ʻIkepili o ka polysaccharide
- Ka hoʻoholo ʻana i ke ʻano o ke kaulahao kō i loko o nā glycoproteins
-Ka helu helu nucleotide
(2) ʻO ka hoʻoholo ʻana o ka hui ʻana
Hiki ke hoʻohana ʻia ke ʻano o ka periodate oxidation e hoʻoholo ai:
- ʻO Glycerol a me kāna mau mea esters
-Alpha amino acid maʻiʻo
- ʻO kekahi mau pūhui phenolic
2. Nā noi ma ka ʻepekema Materials
(1) ʻOihana uila
- Ka mālama ʻana i nā mea semiconductor
-Micro etching of printed circuit boards (PCBs)
-Hoʻomaʻemaʻe ʻāpana uila
(2) Ka hana metala
-Ka lapaʻau passivation o ke kila kuhiliʻole
-ʻO ka hoʻomaʻemaʻe a me ka hoʻomaʻemaʻe mua
-Oxidation kaʻina hana electroplating
3. kahua biomedical
(1) Hoʻopaʻa moʻolelo
ʻO ke ʻano hoʻopaʻa ʻana o ka acid acid Schiff (PAS) kahi hana koʻikoʻi i ka maʻi pathological:
-Hoʻohana ʻia no ka ʻike ʻana i nā polysaccharides a me nā glycoproteins i loko o nā kiko
- Hōʻike i ka membrane basement, fungal cell wall a me nā hale ʻē aʻe
-ʻO ka hōʻailona kōkua o kekahi mau maʻi koko
(2) Nā kaha biomolecular
- Ka nānā ʻana o nā pūnaewele glycosylation protein
-E noiʻi i nā paʻakikī kō ma ka ʻili pūnaewele
4. Nā noi i ka synthesis organik
Ma ke ʻano he oxidant koho, komo ʻo ia i nā ʻano kūlohelohe like ʻole:
-Cis dihydroxylation o olefins
-Ke koho ʻana i nā waiʻona
-Removal reactions o kekahi mau hui pale
Nā mālama palekana
Pono e noʻonoʻo i ka wā e hoʻohana ai i ka waikawa periodic:
1. Corrosivity: ʻO ka corrosiveness ikaika i ka ʻili, nā maka, a me nā membrane mucous
2. He pōʻino o ka hoʻoheheʻe ʻia: Hiki i ke hoʻopili ʻana me nā mea ola i ke ahi a pahū paha
3. Pono e mālama: E mālama i ka mālamalama, hoʻopaʻa ʻia, a ma kahi anuanu
4. Palekana pilikino: I ka wā o nā hana hoʻokolohua, pono e ʻaʻahu ʻia nā goggles pale, nā mīkina lima, a me nā lole pale.
Me ka holomua o nā ʻenehana analytical a me ka hoʻomohala ʻana i ka ʻepekema waiwai, e hoʻonui mau ana nā kahua noi o ka waika periodic.
Nanomaterial synthesis: ma ke ʻano he oxidant i komo i ka hoʻomākaukau ʻana i kekahi mau nanomaterials
Nā ʻenehana kālailai hou: hui pū ʻia me nā mea hana analytical hou e like me mass spectrometry
Kemika ʻōmaʻomaʻo: Ke hoʻomohala nei i kahi kaʻina hana ʻoi aku ka maikaʻi no ka hana hou ʻana a me ka hoʻohana hou ʻana i ka waika manawa
ʻO Periodate, ma ke ʻano he oxidant kūpono a kikoʻī, hoʻokani i kahi hana hiki ʻole ke hoʻololi ʻia i nā ʻano like ʻole mai ka noiʻi kumu a hiki i ka hana ʻenehana.
