Yuav ua li cas siv pH composite electrodes kom raug?
(1) Yuav tsum tsis muaj npuas nyob rau pem hauv ntej ntawm lub npuas, thiab yog tias muaj npuas, lawv yuav tsum tau quab yuam pov tseg.
(2) Tom qab cov electrode raug tshem tawm ntawm lub raj mis soaking, nws yuav tsum tau shaken thiab qhuav hauv dej deionized. Tsis txhob so lub teeb nrog daim ntawv phuam. Txwv tsis pub, vim hais tias tus nqi electrostatic induction yog pauv mus rau iav zaj duab xis, lub sij hawm ntawm kev ruaj ntseg yuav ntev. Txoj kev zoo dua yog siv cov tshuaj ntsuas los ntxuav cov electrode.
(3) Tom qab muab cov pH sib xyaw electrode rau hauv cov tshuaj ntsuas, nws yuav tsum tau nplawm thiab shaken ob peb zaug ua ntej sawv ntsug, uas yuav ua kom cov electrode teb sai. Tshwj xeeb tshaj yog thaum siv lub plhaub yas pH sib xyaw electrodes, nplawm thiab co yog qhov hnyav dua vim tias muaj cov kab noj me me ntawm lub pob npuas thiab lub plhaub yas. Tom qab cov electrode yog immersed nyob rau hauv cov kev daws teeb meem, qee zaum cov roj hauv cov kab noj hniav tsis tuaj yeem raug tshem tawm hauv lub sijhawm, ua rau muaj npuas, uas ua rau kev sib cuag tsis zoo ntawm lub pob npuas los yog kua interface thiab cov tshuaj. Yog li ntawd, muaj zog stirring thiab co yog tsim nyog los tshem tawm npuas.
(4) Tom qab kuaj hauv cov qauv viscous, cov electrode yuav tsum tau rov qab yaug nrog dej deionized ntau zaus kom tshem tawm cov qauv ua raws li cov iav zaj duab xis. Qee lub sij hawm nws yog ib qho tsim nyog yuav tsum xub ntxuav cov qauv nrog lwm cov reagents, tom qab ntawd ntxuav cov kuab tshuaj nrog dej, thiab muab tso rau hauv cov kua dej kom ua kom muaj zog.
(5) Tsis txhob sib cuag nrog cov kua qaub uas muaj zog, alkalis, lossis cov tshuaj corrosive. Yog tias kuaj cov kev daws teeb meem zoo li no, sim txo lub sij hawm immersion thiab ua tib zoo ntxuav lawv tom qab siv.
(6) Tsis txhob siv rau hauv lub cev qhuav dej xws li anhydrous ethanol thiab concentrated sulfuric acid, uas yuav ua rau cov hydrated gel txheej rau ntawm qhov muag teeb.
(7) Lub plhaub ntawm cov ntaub ntawv molded pH composite electrode yog polycarbonate yas (PC) PC yas uas yuav yaj nyob rau hauv ib co kuab tshuaj, xws li carbon tetrachloride, Trichloroethylene, tetrahydrofuran, thiab lwm yam. electrode plhaub yuav tsim. Lub sijhawm no, cov ntaub ntawv iav pH puas electrode yuav tsum tau siv los hloov.
