Vim li cas thiaj ua rau cov me me hluav taws xob yuav tsum tau soaked nyob rau hauv poov tshuaj tshuaj chloride?
Dab tsi yog phaj meter electrode?
Lub ntsiab mot electrode muaj kev siv electrode thiab lub iav electrode. Qhov kev siv hluav taws xob hluav taws xob feem ntau muaj cov tshuaj sab hauv, thaum lub iav electrode muaj cov yeeb yaj kiab iav siv rau kev xav txog hydrogen ions hauv kev daws teeb meem. Tus txheej txheem ua hauj lwm ntawm PHO MOAV ELECTODES yog ua raws Electrochemical cov tshuaj tiv thaiv. Thaum lub electrode yog tso rau hauv kev ntsuas ntsuas dej, hydrogen ions hauv kev daws teeb meem dab nrog cov iav membrane los tsim lub peev xwm sib txawv. Lub ntsuas me me suav nrog kev daws teeb meem los ntawm kev ntsuas qhov sib txawv no.
Qhov tseem ceeb ntawm soaking hauv poov tshuaj tshuaj chloride
1. Tswj cov concentration ntawm electrode siv cov tshuaj: Qhov kev siv elotassium feem ntau muaj qhov sib npaug ntawm cov tshuaj potassium chloride sab hauv thiab sab nraud qhov kev siv hluav taws xob. Yog tias lub electrode tsis yog raus hauv poov tshuaj tshuaj tov, cov lus qhia daws nyob rau hauv electrode tej zaum yuav maj mam pom ntawm cov kev daws teeb meem thiab cuam tshuam rau qhov tseeb ntawm cov ntsuas ntsuas.
2. Zam hluav taws xob ziab: lub ntsuas hluav taws xob rau hluav taws xob, tshwj xeeb tshaj yog iav zaj duab xis ib feem, yuav tsum tau khaws cia noo noo. Muaj ib txheej hydration nyob rau hauv daim iav zaj duab xis, uas yog qhov tseem ceeb rau cov electrode kom pom ntawm hydrogen ions. Yog tias electrode rau huab cua rau lub sij hawm ntev yam tsis tau khaws cov txheej uas ntub dej yuav qhuav, ua rau qeeb hauv cov lus teb thiab ntsuas tsis muaj tseeb. So rau hauv cov poov tshuaj vloride daws tau tuaj yeem tiv thaiv kom qhuav kom qhuav thiab tswj nws qhov kev paub zoo.
3. Txo cov nyiaj tso tawm ntawm cov impurities hauv elecodes: hauv kev siv txhua hnub, hluav taws xob tuaj yeem nkag mus rau ntau cov kev daws teeb meem uas yuav muaj ntau yam impurities. Yog tias cov tshuaj ntxuav poov tshuaj tsis tu ncua, cov impurities yuav nthuav tawm tsis tu ncua lossis sab hauv ntawm electrode, cuam tshuam rau kev ntsuas kev ntsuas ntawm electrode. Poov tshuaj tshuaj chloride daws tau tuaj yeem tshem tawm cov impurities thiab khaws cov electrode huv.
4. Txuas ntxiv cov kev pabcuam lub neej ntawm cov electrodes: • Meter electrodes yog consumables yog cov neeg siv tau, qhov tseeb ntawm cov electrodes yuav maj mam poob. Los ntawm kev nquag ua rau hauv poov tshuaj tshuaj dawb, cov txheej txheem no tuaj yeem ncua kev pabcuam lub neej ntawm electrode thiab txo qhov zaus ntawm cov khoom siv hluav taws xob.
Yuav ua li cas kom kom zoo li luak lub pot meter electrode?
1. Xaiv ib qho tsim nyog concassium tshuaj tov tshuaj: Feem ntau, ib qho tshuaj pleev li ntawm 3.5 M poov tshuaj Txoj kev daws tau zoo, uas phim cov kev daws teeb meem hauv feem ntau ntawm cov meter hluav taws xob.
2. Nquag hloov cov tshuaj soaking: kom muaj cov xwm txheej ua kom muaj kev sib txuam tsis tu ncua los tiv thaiv kom tsis txhob muaj kev cuam tshuam nrog kev daws teeb meem ntev.
3. Zam kev siv cov dej distilled: Tom qab ntxuav cov hluav taws xob nrog cov hluav taws xob tsis zoo, cov electrode yuav tsum tau tsau rau hauv dej sab hauv kom ntev. Ntev lub sij hawm immersion hauv distilled dej yuav dhuav cov poov tshuaj tshuaj dawb hauv electrode, yog li cuam tshuam kev ntsuas qhov tseeb.
