Vim li cas yuav tsum pH meter electrodes yuav tsum tau soaked nyob rau hauv poov tshuaj chloride tov?
Lub pH meter electrode yog qhov ntsuas qhov tseeb, nws lub luag haujlwm tseem ceeb yog ntsuas cov kua qaub thiab alkalinity (pH tus nqi) ntawm cov tshuaj. Txhawm rau kom ntseeg tau qhov tseeb ntawm kev ntsuas thiab txuas ntxiv lub neej kev pabcuam ntawm electrodes, kev saib xyuas tsim nyog thiab kev saib xyuas yuav tsum tau ua ntawm cov electrodes. Soaking pH meter electrode hauv cov tshuaj potassium chloride (KCl) yog ib qho tseem ceeb ntawm kev saib xyuas. Kab lus no yuav piav qhia meej tias vim li cas pH meter electrodes yuav tsum tau soaked nyob rau hauv poov tshuaj chloride thiab tshawb nrhiav cov hauv paus ntsiab lus ntawm cov txheej txheem no.
Dab tsi yog pH meter electrode?
Lub pH meter electrode muaj ib qho siv electrode thiab iav electrode. Cov electrode siv feem ntau muaj cov tshuaj siv sab hauv, thaum lub iav electrode muaj cov iav zaj duab xis siv los txiav txim siab qhov concentration ntawm hydrogen ions hauv cov tshuaj. Lub hauv paus ntsiab lus ua haujlwm ntawm pH meter electrodes yog raws li cov tshuaj tiv thaiv electrochemical. Thaum cov electrode yog immersed nyob rau hauv cov kev ntsuas ntsuas, hydrogen ions nyob rau hauv cov tshuaj reacts nrog lub iav daim nyias nyias los tsim ib tug muaj peev xwm sib txawv. Lub pH ntsuas ntsuas pH tus nqi ntawm cov tshuaj los ntawm kev ntsuas qhov sib txawv qhov sib txawv.
Qhov tseem ceeb ntawm soaking hauv poov tshuaj chloride
1. Khaws cov concentration ntawm cov tshuaj siv electrode: Cov khoom siv electrode ntawm pH meter feem ntau muaj cov tshuaj potassium chloride, thiab soaking hauv cov tshuaj potassium chloride yog kom muaj qhov sib npaug ntawm cov poov tshuaj chloride concentration sab hauv thiab sab nraud cov ntaub ntawv electrode. Yog hais tias cov electrode tsis nyob rau hauv cov tshuaj poov tshuaj chloride, cov tshuaj siv nyob rau hauv cov electrode yuav maj mam nkag mus rau hauv lub pores nyob rau hauv lub electrode, ua rau tsis ruaj tsis khov concentration ntawm cov ntaub ntawv siv tshuaj thiab cuam tshuam qhov tseeb ntawm pH ntsuas.
2. Tsis txhob qhuav electrode: pH meter electrode, tshwj xeeb tshaj yog cov iav zaj duab xis, yuav tsum tau khaws cia noo. Muaj txheej hydration nyob rau hauv cov iav zaj duab xis, uas yog ib qho tseem ceeb rau electrode nrhiav kom tau hydrogen ions. Yog tias cov electrode raug huab cua ntev ntev yam tsis tau khaws cia, cov txheej txheem dej yuav qhuav, ua rau qeeb electrode teb thiab ntsuas tsis raug. Soaking hauv cov tshuaj poov tshuaj chloride tuaj yeem tiv thaiv electrode kom qhuav thiab tswj nws qhov rhiab heev.
3. Txo cov deposition ntawm impurities nyob rau hauv electrodes: Nyob rau hauv niaj hnub siv, electrodes yuav tuaj mus rau hauv kev sib cuag nrog ntau yam kev daws teeb meem uas yuav muaj ntau yam impurities. Yog tias cov tshuaj poov tshuaj chloride immersion tsis ua haujlwm tsis tu ncua, cov impurities no tuaj yeem sau rau ntawm qhov chaw lossis sab hauv ntawm electrode, cuam tshuam rau kev ntsuas kev ua haujlwm ntawm electrode. Potassium chloride tov tuaj yeem tshem tawm cov impurities zoo thiab ua kom cov electrode huv si.
4. Extending lub neej kev pab cuam ntawm electrodes: pH meter electrodes yog consumables, thiab raws li lub sij hawm siv nce, qhov rhiab heev thiab raug ntawm cov electrodes yuav maj mam txo. Los ntawm tsis tu ncua soaking nyob rau hauv cov tshuaj poov tshuaj chloride, cov txheej txheem no yuav ua tau zoo ncua, ncua lub neej kev pab cuam ntawm lub electrode thiab txo qhov zaus ntawm electrode hloov.
