Puas muaj lub sijhawm txwv rau soaking cov electrodes hauv cov tshuaj thaum siv lub ntsuas pH
Lub pH meter / acidimeter electrode yuav tsum tau ntub dej ua ntej siv, vim tias pH meter / acidimeter noob yog ib hom iav tshwj xeeb, thiab muaj cov txheej nyias nyias nyias ntawm cov iav zaj duab xis, uas tuaj yeem muaj cov lus teb zoo. rau H + ions hauv cov tshuaj tsuas yog thaum nws ntub tag nrho. Nyob rau tib lub sijhawm, cov iav electrode tuaj yeem txo qhov peev xwm asymmetric thiab zoo li ruaj khov tom qab soaked. Lub pH meter / acidimeter iav electrode feem ntau tuaj yeem tsau nrog dej distilled lossis pH meter / acidimeter 4 tsis muaj tshuaj. Nws yog qhov zoo dua los siv pH meter / acidimeter 4 tsis siv tshuaj, thiab lub sijhawm immersion yog 8 teev mus rau 24 teev lossis ntev dua, nyob ntawm qhov tuab ntawm lub teeb iav zaj duab xis thiab qib ntawm electrode aging. Nyob rau tib lub sijhawm, Cov kua dej sib txuas ntawm cov khoom siv electrode kuj yuav tsum tau ntub dej. Vim hais tias yog cov kua hlws ris dries, cov kua hlws ris tej zaum yuav nce los yog tsis ruaj khov. Cov tshuaj immersion ntawm cov ntaub ntawv siv electrode yuav tsum ua raws li cov lus qhia sab nraud ntawm cov khoom siv electrode, A 3.3mol / L KCL tov lossis saturated KCL tov yog feem ntau txaus rau soaking rau ob peb teev. Yog li ntawd, rau pH / acidity meter composite electrodes, lawv yuav tsum tau tsau rau hauv pH / acidity meter 4 tsis muaj tshuaj uas muaj KCL thiaj li ua hauj lwm ntawm ob lub iav qhov muag teev thiab cov kua interface ib txhij. Kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov no vim tias yav dhau los, tib neeg siv los ntub ib qho pH / acidity meter iav electrodes hauv dej deionized lossis pH / acidity meter 4 tsis muaj tshuaj. Tom qab ntawd, txoj kev ntub dej no tseem siv tau thaum siv pH / acidity meter composite electrodes, thiab txawm tias cov lus qhia tsis raug tau muab rau hauv cov neeg siv phau ntawv ntawm qee qhov tsis raug pH / acidity meter composite electrodes. Txoj kev ntub dej tsis raug no tau ua rau muaj teeb meem. Qhov txiaj ntsig ncaj qha yog qhov ua tau zoo pH / acidity meter composite electrode dhau los ua cov lus teb qeeb thiab tsis raug electrode, Ntxiv mus, lub sijhawm ntub dej ntev dua, qhov ua tau zoo dua, vim tias tom qab lub sij hawm ntub dej ntev, KCL concentration hauv cov kua dej sib txuas. (xws li hauv cov xuab zeb core) tau txo qis heev, ua rau muaj kev nce ntxiv thiab tsis ruaj khov hauv cov kua dej sib cuam tshuam. Tau kawg, tsuav yog cov electrode rov qab tsau rau hauv cov kua dej kom raug rau ob peb teev, nws tseem yuav rov zoo.
Tsis tas li ntawd, pH / acidity meter electrodes yuav tsum tsis txhob muab tso rau hauv nruab nrab lossis alkaline tsis daws teeb meem. Lub sij hawm ntev immersion hauv cov kev daws teeb meem no tuaj yeem ua rau lub pH / acidity meter iav daim nyias nyias los teb qeeb. Kev npaj kom raug ntawm pH / acidity meter electrode immersion tov: Siv ib pob ntawm pH / acidity meter 4.00 tsis (250ml), yaj nyob rau hauv 250ml ntawm dej ntshiab, ntxiv 56g ntawm analytical qib KCl, cua sov kom tsim nyog. , thiab do kom txog thaum yaj tag. Lub raj mis electrode immersion daws muaj nyob rau hauv kev ua lag luam, nrog specifications ntawm 500ml thiab 50ml. Cov kev daws teeb meem immersion no muaj cov khoom siv khaws cia thiab yuav tsis tuaj pwm lossis tsis zoo, nrog lub txee lub neej ntawm ib xyoos.
Txhawm rau ua kom siv pH / acidity meter composite electrodes yooj yim dua, qee qhov pH / acidity meter composite electrodes thiab qee cov khoom siv hluav taws xob hauv tsev tau nruab nrog lub raj mis yas kaw ntawm lub taub hau ntawm pH / acidity meter composite electrode, uas muaj cov electrode. soaking tshuaj. Lub taub hau electrode yog tsau rau hauv nws ntev thiab tuaj yeem tshem tawm thiab ntxuav thaum siv, uas yooj yim heev. Txoj kev khaws cia no tsis yog yooj yim xwb, tab sis kuj tseem muaj txiaj ntsig zoo rau kev ncua lub neej electrode. Txawm li cas los xij, cov tshuaj soaking hauv lub raj mis yas yuav tsum tsis txhob muaj kab mob thiab yuav tsum tau hloov kom zoo
