Kev siv cov pH sib xyaw 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 tshem cov electrode los ntawm lub raj mis soaking, nws yuav tsum tau shaken nyob rau hauv dej deionized thiab shaken qhuav. Tsis txhob so lub teeb nrog daim ntawv phuam, txwv tsis pub tus nqi hluav taws xob electrostatic yuav hloov mus rau iav zaj duab xis, uas yuav ua rau lub sijhawm ntev rau kev ruaj ntseg. Ib txoj hauv kev zoo dua yog yaug cov electrode nrog cov tshuaj ntsuam xyuas.
(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 khoom ntawm lub plhaub yas pH sib xyaw electrode yog polycarbonate yas (PC). PC yas yuav yaj hauv qee cov kuab tshuaj, xws li carbon tetrachloride, trichloroethylene, tetrahydrofuran, thiab lwm yam. Yog tias cov kuab tshuaj saum toj no suav nrog hauv kev sim, lub plhaub electrode yuav raug tsim. Nyob rau lub sijhawm no, pH electrode sib xyaw nrog lub iav plhaub yuav tsum tau siv los hloov.
