A fluoride selective electrode yog hom ion xaiv electrode rhiab rau qhov concentration ntawm fluoride ion. Ib qho piv txwv yog lanthanum fluoride electrode.
Txoj cai ntawm ion xaiv electrode yog dab tsi?
Txoj cai ntawm ion-xaiv electrode (I. S. E.) … muaj ntawm ib daim nyias nyias hla uas tsuas yog cov ion npaj tuaj yeem thauj tau. Kev thauj mus los ntawm ions los ntawm lub siab conc. mus rau ib qho qis los ntawm kev xaiv khi nrog qee qhov chaw hauv daim nyias nyias tsim qhov sib txawv.
PH twg yog qhov haum rau fluoride ion xaiv electrode?
pH Range: Cov Fluoride Electrode yuav tsum tau siv nyob rau hauv pH ntau 4-9 txhawm rau tshem tawm OH- cuam tshuam. Sijhawm: hauv kev daws hauv tsawg dua 4s. Thaum, txawm li cas los xij, cov electrode raug tshem tawm ntawm ib qho kev daws thiab muab tso rau hauv lwm qhov sib txawv ntawm cov tshuaj fluoride, nws yuav siv sij hawm txog 30s kom sib npaug.
Qhov twg hauv qab no yog Ion Selective Electrode?
iav membranes
Chalcogenide iav kuj tseem muaj kev xaiv rau ob chav them hlau ions, xws li Pb2 +, and Cd2+. Cov iav membrane muaj cov tshuaj tiv thaiv zoo heev thiab tuaj yeem ua haujlwm hauv kev tawm tsam hnyav heev. Ib qho piv txwv ntawm hom electrode no yog pH iav electrode.
Vim li cas iav electrode hu ua ion-xaiv electrode?
iav electrodes yog ion-xaiv electrodes raws li cov khoom siv tshuaj ntawm lub iav daim nyias nyias ntawm cov tshuaj muaj pes tsawg leeg. Kev coj mus rau hauv cov iav qhuav yog vim qhov cation ntawm tus nqi qis tshaj plaws thiab tsis cuam tshuam txog kev nkag mus los ntawm ntau qhov cations. … Figure 16.

Nyob rau hauv cov ntsiab lus ntawm pej xeem lub tswv yim kev xaiv tsa yog dab tsi yog tus kheej xaiv?
nyob rau hauv cov ntsiab lus ntawm kev xaiv tsa pej xeem, xaiv tus kheej yog dab tsi? Raws li kev xaiv tsa rau Smart Polling, koj yog txhawj xeeb txog kev ntsuas cov pej xeem tus cwj pwm ntawm caj npab-tswj txoj cai, vim koj ntseeg tias cov pej xeem tsis tsuas muaj cov ntaub ntawv me me ntawm cov ncauj lus nyuaj no tab sis kuj tau xav.
Hauv iav electrode lub sab hauv siv electrode yog?
internal electrode, feem ntau silver chloride electrode lossis calomel electrode. cov tshuaj sab hauv, feem ntau yog pH=7 buffered tov ntawm 0.1 mol / L KCl rau pH electrodes los yog 0.1 mol / L MCl rau pM electrodes. Thaum siv cov nyiaj chloride electrode, ib qho me me ntawm AgCl tuaj yeem ua rau hauv cov iav electrode.
Los ntawm xaiv xaiv xaiv?
Cov ntsiab lus yog txhua yam sib txawv grammatical ntawm tib cov lus qhia. "Xaiv" yog ib qho kev qhia tsis sib xws, nrog"xaiv" raws li daim ntawv dhau los yav dhau los daim ntawv Passer hauv Yav dhau los Tense Muab tso ua ke yog qhov yooj yim heev:
Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau pom kev pom?
Txawm li cas los xij, corneal collagen cross-linking - cov txheej txheem qib siab tau pom zoo los ntawm US Food and Drug Administration (FDA) hauv xyoo 2016 - tuaj yeem txhim kho qhov pom kev hauv cov neeg mob txhua hnub nyoog. Corneal collagen cross-linking (CXL) tsis yog kho rau keratoconus, tab sis nws tuaj yeem pab tiv thaiv tus mob kom tsis txhob mob hnyav.
Leej twg detering nyob rau hauv tag nrho cov nyob ntsiag to nyob rau sab hnub poob pem hauv ntej?
Detering yog tus neeg ua liaj ua teb los ntawm Txhua Tus Neeg Tsis Txaus Siabntawm Sab Hnub Poob los ntawm Erich Maria Remarque. Nws muaj siab mos siab muag, tshwj xeeb tshaj yog thaum nws los txog rau nees. Nws muaj kev kub ntxhov loj heev thaum nws hnov cov nees quaj thiab txawm sim tua lawv kom kawg lawv txoj kev txom nyem.
