Dab tsi yog kev siv iav electrode ntawm pH meter?
1. Thaum lub sij hawm ntsuas, lub teeb ntawm lub iav electrode ntawm online pH meter yuav tsum tau muab tso rau hauv qhov kev daws teeb meem, kom nws siab dua me ntsis ntawm cov tub ntxhais ceramic kawg ntawm calomel electrode.
2. Thaum ntsuas, siv cov sib nqus stirrer los do ntawm qhov tsim nyog ceev. Lub stirring ceev yuav tsum tsis txhob ceev heev, txwv tsis pub huab cua npuas yuav raug generated thiab txuas mus rau cov electrodes, uas ua rau cov nyeem tsis ruaj khov.
3. Thaum ntsuas cov qauv oily, tshwj xeeb tshaj yog cov roj slick, ntxuav lawv nrog CCI4 lossis acetone tom qab siv;
Tom qab ntawd, nws yuav tsum tau muab yaug nrog 1.2mol / L hydrochloric acid, ces yaug nrog dej distilled, soaked nyob rau hauv dej distilled kom sib npaug rau ib hnub thiab hmo ntuj ua ntej siv.
4. Tom qab ntsuas cov kua turbid, yaug nws nrog dej distilled raws sij hawm.
5. Tom qab ntsuas cov tshuaj emulsified, ntxuav lub electrode nrog xab npum thiab dej distilled nyob rau hauv lub sij hawm, thiab ces tsau rau hauv dej distilled.
6. Yuav tsum tsis txhob muaj cua npuas nruab nrab ntawm lub puab electrode ntawm iav electrode ntawm pH meter online thiab lub teeb. Yog tias muaj huab cua npuas, co me ntsis kom cov pa npuas khiav dim.
7. Cov electrodes ntawm lub pH meter tshiab online yuav tsum tau kho thiab tsau rau hauv cov dej distilled rau ib lub sij hawm los tsim ib txheej hydration zoo;
Lub sij hawm immersion muaj feem xyuam rau cov iav thiab lub thickness ntawm zaj duab xis. Feem ntau, lub sij hawm immersion rau cov electrodes tshiab thiab electrodes uas tsis muaj iav conductivity thiab thicker zaj duab xis yog 24 teev; txwv tsis pub, lub sij hawm immersion yuav luv dua.
Vim yog kev txhim kho cov iav zoo thiab cov txheej txheem tsim khoom, cov pH meter online electrodes uas siv rau thawj zaug lossis tsis siv rau lub sijhawm ntev yog qhia hauv phau ntawv;
Thaum siv, tsuas yog tsau rau hauv 3N KCL tov los yog dej deionized rau 2-10 teev.
8. Tom qab kev txiav txim siab ntawm ib qho kev daws teeb meem tiav, ua tib zoo yaug kom zoo, ua kom cov dej ntws tawm, thiab ntsuas cov qauv tom ntej.
