Redox

Neqiniso redox kuyinto ezingaba kagesi oluhlala le electrode ibekwa isixazululo equkethe ethile redox izinhlelo. izinhlelo ezinjalo, elifushane, isihloko uzobe ukubizwa ngokuthi OBC. Isimo ezidingekayo ukuze kwakhiwe futhi ukulungisa isakhiwo esinjalo ukuthi electrode ukuba lapho kwenzeka, bekulokhu metal inert.

SMF esethola, noma redox uhlelo, - yisisombululo lapho izidakamizwa likhona esifika oxidized futhi yehlise kanyekanye. Ngayinye yalezi amafomu iwukuba zimiswe kusuka kwenye ngokuhamba ukusabela uhlobo redox. Omunye izwi, ifomu izinto ekhona ikhambi elinjalo, kuyakuba engase emuva. Isibonelo elula kohlelo redox yisisombululo lapho kukhona anions noma cations elilodwa lensimbi, kodwa valency zabo zihlukile.

In izinhlelo ezinjalo, aphuma ifomu eyodwa kuya kwenye imfuyo wenziwa esebenzisa ukudluliswa electron e isiqondiso esivela efomini encishisiwe. izinhlelo ezinjalo ezinye enzyme zokuphefumula, okuyinto ukubunjwa yayo iqukethe hemin. amakhono abo redox kunqunywa ngokuhambisana nemithetho evulekile Claus Peters. Ezweni begazi, kukhona imali eyanele redox izinhlelo, lapho ushintsho Kwenziwa hhayi ukudluliselwa electron, kodwa nenani elilinganako proton.

Ngaphansi kwezimo zelabhorathri bezikhali redox kunqunywa kusetshenziswa indlela potentiometric. ubuchwepheshe Its kanje: Kokubili electrode inert iqale afakwe ikhambi efanayo, bese izixazululo ahlukahlukene, kodwa okuyizinto oxhumene isibopho electrolytic okuvumela izixazululo uhlanganise. Kusukela inani umehluko kunqunywa izakhi ukudluliswa kanye ukubaluleka ezingaba khona.

Ukukala futhi wasebenzisa indlela Colorimetric lapho nesilinganiso Kwenziwa izinkomba ekhethekile.

Kungakhathaliseki uhlobo nezilinganiso kuqondwe ukuthi ukubaluleka kwengosi kuba redox izenzo ezingase zibe njengoba inkomba jikelele okuzivuselela uhlelo izakhiwo redox, futhi namachibi ayo umthamo. Mechanism ezidlulayo inqubo redox ilula ngokwanele ukuthi bangaqonda. Esikhathini kohlaka SMF nge engaba ephakeme, oxidizes le SMF, okuyinto has a engaba redox ezidlula kancane. Ukumeda ngokuhlukumeza okunamandla inquma ubungako bamandla okuyinto eziqukethwe izinqubo redox ezenzeka ngokwemvelo.

Lezi zinqubo ukunikeza ukhona umzimba ngamunye ngoba lesibopho electron ukunyakaza, futhi ngenxa yalokho, lapho kukhululwa ethile amandla ukulondoloza homeostasis cell ukuvuselelwa.

Ngokwesibonelo, evamile, noma ejwayelekile redox bezikhali enkulu yomzimba womuntu yakhiwa kuleli uhla - 200 mV - + 100 mV, okubonisa ukuthi imvelo ukuncipha imvelo yangaphakathi. Lapho yokulinganisa ezingaba, kufanele ukwanelisa isimo: ukuthola okunokwethenjelwa idatha ukuqhathanisa, izilinganiso kufanele kwenziwe ngaphansi esifanayo izimo physico-amakhemikhali. Uma efanayo ngoba umzimba womuntu, izimo ukulinganisa ezingaba redox emanzini, kungenzeka ukuthola ukuthi inani layo cishe njalo omuhle futhi value-200 kuya ku-300 mV. -ke leyo e abakuzuzile umthamo wamanzi umzimba womuntu, bathi ama-electron, emzimbeni liziphathe asebenzayo okuningi kuka ku isixazululo aqueous. Cishe, lokhu kusho ukuthi amanzi ne izinkomba ezinjalo, ngokufaka inqubo namachibi umzimba womuntu ungena ngqo.

Le mpahla isetshenziselwa ukulungiswa izinkomba ezinjalo OBC, eliwumzimba yethu. Amanzi, kokuba negative Inkomba ezingaba, isetshenziswa njengoba isici esiyinhloko (futhi ngokuzimela) ukulungiswa izidakamizwa ukuthi ekulinganiseni ibhalansi redox.
