asiti ea nako le nako(HIO ₄) ke asiti e matla ea bohlokoa e sa pheleng e nang le mefuta e mengata ea ts'ebeliso e le oxidant masimong a fapaneng a saense le a indasteri. Sengoloa sena se tla fana ka selelekela se qaqileng mabapi le litšobotsi tsa motsoako ona o ikhethang le ts'ebeliso ea oona ea bohlokoa masimong a fapaneng.
Thepa ea lik'hemik'hale ea asiti ea periodic
Periodidate ke asiti e nang le oksijene e phahameng ka ho fetisisa e nang le boemo ba oxidation ea iodine (+7 valence), hangata e fumaneha ka likristale tse se nang 'mala kapa foromo ea phofo e tšoeu. E na le litšobotsi tse latelang tsa bohlokoa:
Bokhoni bo matla ba ho eketsa oxidizing:Ka bokgoni bo tloaelehileng ba phokotso ba ho fihlela ho 1.6V, e ka kopanya metsoako e fapaneng ya tlhaho le e seng ya tlhaho
Ho qhibiliha ha metsi:E qhibiliha haholo metsing, e etsa tharollo e se nang 'mala
Ho se tsitse ha mocheso:e tla bola ha e futhumatsoa ka holimo ho 100 ° C
Asiti:ke ea asiti e matla, e arohana ka ho feletseng tharollong ea metsi
Libaka tse ka sehloohong tsa kopo
1. Likopo ho Khemistri ea Tlhahlobo
(1) Karabelo ea Malaprade
Tšebeliso e tsebahalang haholo ea asiti ea nako le nako ke tlhahlobong ea lik'hemik'hale ea lik'habohaedreite. E ka oxidize le ho roba ka ho khetheha meaho ea diol e haufi (joalo ka li-cis diol limolek'huleng tsa lik'habohaedreite) ho hlahisa li-aldehyde kapa li-ketone tse tsamaellanang. Karabelo ena e sebelisoa haholo bakeng sa:
-Tlhahlobo ea sebopeho sa polysaccharide
-Ho tseba sebopeho sa ketane ea tsoekere ka har'a li-glycoprotein
Tlhahlobo ea tatellano ea nucleotide
(2) Ho fumana motsoako oa lintho tse phelang
Mokhoa oa oxidation oa periodate o ka sebelisoa ho fumana:
-Glycerol le dikahare tsa yona tsa ester
- Bongata ba amino acid ea alpha
-Metsoako e itseng ea phenolic
2. Likopo ho Saense ea Lisebelisoa
(1) Indasteri ea elektroniki
-Tlhabollo ea thepa ea semiconductor holim'a bokaholimo
-Ho qoelisoa ha diboto tsa potoloho tse hatisitsoeng (di-PCB) ka micro etching (ho qoelisoa ha diboto tsa potoloho tse nyane)
-Ho hlwekisa dikarolo tsa elektroniki
(2) Ts'ebetso ea tšepe
-Tlhabollo ea ho se sebetse holim'a tšepe e sa hloekang
-Tlhoekiso ea bokaholimo ba tšepe le kalafo ea pele
-Mehato ea ho kenya oksijene ts'ebetsong ea electroplating
3. Tšimo ea bongaka
(1) Matheba a histological
Mokhoa oa ho taka oa periodic acid Schiff (PAS) ke mokhoa oa bohlokoa oa ho hlahloba lefu la pathological:
-E sebelisetsoa ho lemoha li-polysaccharides le li-glycoprotein liseleng
-Pontšo ea lera la ka tlas'a lefatše, lebota la sele ea fungal le meaho e meng
-Tlhahlobo e thusang ea lihlahala tse itseng
(2) Matšoao a limolek'hule
-Tlhahlobo ea libaka tsa glycosylation ea protheine
-Patlisiso mabapi le metsoako ea tsoekere holim'a bokaholimo ba sele
4. Ditshebediso tsa tlhahiso ya dintho tse phelang
Jwalo ka oxidant e kgethang, e nka karolo dikarabelong tse fapaneng tsa tlhaho:
-Cis dihydroxylation ea olefin
-Khetho ea oxidation ea alcohols
-Ts'ebetso ea ho tlosa lihlopha tse itseng tsa tšireletso
Mehato ea tšireletso
Ela hloko ha o sebelisa asiti ea periodic:
1. Ho bola: Ho bola ho matla letlalong, mahlong le lera la mucous
2. Kotsi ea oxidation: Ho kopana le lintho tse phelang ho ka baka mollo kapa ho phatloha
3. Litlhoko tsa polokelo: Boloka hole le khanya, e koetsoe, 'me e be sebakeng se pholileng
4. Tšireletso ea botho: Nakong ea ts'ebetso ea liteko, likhalase tsa tšireletso, liatlana le liaparo tse sireletsang li lokela ho aparoa
Ka tsoelo-pele ea mekhoa ea tlhahlobo le nts'etsopele ea mahlale a thepa, masimo a ts'ebeliso ea asiti ea periodic a ntse a atoloha.
Ho kopanngoa ha lintho tse ling: e le oxidant e amehang ho lokiseng lintho tse ling tse ling tse ling
Mekhoa e mecha ea tlhahlobo: e kopantsoe le lisebelisoa tsa sejoale-joale tsa tlhahlobo tse kang mass spectrometry
Khemistri e Tala: Ho ntshetsa pele mokgwa o mosa haholoanyane tikolohong bakeng sa ho sebedisa hape le ho sebedisa hape asiti ya nako le nako
Periodate, e le oxidant e sebetsang hantle le e ikhethang, e bapala karolo e ke keng ea nkeloa sebaka masimong a fapaneng ho tloha lipatlisisong tsa motheo ho isa tlhahisong ea indasteri.
