Vim li cas thiaj yuav tsum ph elec elecrodes yuav tsau? Yuav ua li cas kom zoo li soak ph tuaj ntxiv hluav taws xob?
Lub P Electrode yuav tsum tau soaked ua ntej siv, vim tias PHB TXHUA yog ib khob cov iav tshwj xeeb. Muaj ib qho yooj yim heev gel txheej rau saum npoo ntawm lub khob membrane. Nws tuaj yeem muaj cov nyhuv zoo ntawm hydrogen ion hauv kev daws tsuas yog thaum nws ntub dej. Lub caij no, soaking lub iav electrode tuaj yeem txo cov asymmetric muaj peev xwm thiab ruaj khov nws. Ph ntawv cov iav hluav taws xob feem ntau tuaj yeem ua kom dej ntws los ntawm cov dej lossis ph 4.00 buffer daws. Nws yog feem ntau zoo dua rau soak nyob rau hauv ib tug ph 4.00 buffer daws rau 24 teev lossis ntev dua, nyob ntawm qhov tuab ntawm iav zaj duab xis thiab qib ntsuas ntawm electrode kev laus. Nyob rau tib lub sijhawm, cov kua hauv cov khoom siv hluav taws xob ntawm kev siv hluav taws xob txuas ntxiv kuj yuav tsum tau tsau. Vim tias yog tias cov kua interface dries li, lub peev xwm ntawm cov kua interface yuav nce lossis ua tsis tau. Yog li ntawd, cov tshuaj soaking ntawm kev siv elettrode yuav tsum muaj kev daws teeb meem sab nraud, uas yog 3.3Mol / L KCL daws tau cov tshuaj khov kho. Lub sijhawm soaking feem ntau yog ob peb teev.
Yog li ntawd, rau cov hluav taws xob p p p p pawj, lawv yuav tsum tau raus rau hauv cov tshuaj PH 4.00 muaj kev cuam tshuam rau ib txhij rau ib lub teeb rau ob qho tib si ntawm lub khob thiab cov kua interface. Saib xyuas tshwj xeeb yuav tsum tau them rau ntawm no, raws li yav dhau los, tib neeg tau swm rau sokics ib qho dej hauv cov dej lossis ph 4 fuffer daws. Tom qab ntawd, thaum siv cov elosite p p pawj, cov txheej txheem no tseem siv, thiab txawm tias tsis muaj tseeb ntawm cov neeg siv khoom siv hluav taws xob tsis raug. Qhov tseeb ntawm qhov kev ua txhaum cai ntawm qhov no tsis muaj tseeb rau electrode nrog kev ua tau zoo rau electrode nrog qeeb teb thiab raug tsis zoo. Ntxiv mus, ntev dua lub sijhawm so, vim tias tom qab lub sijhawm ntev dhau los, cov KCl Mancing sab hauv cov tub ntxhais xuab zeb) tau txo qis, ua rau muaj peev xwm nce thiab tsis txaus ntawm cov kua interface muaj peev xwm. Tau kawg, ntev npaum li lub electrode yog muab soaked nyob rau hauv qhov tseeb soaking daws rau ob peb teev, nws yuav tseem rov qab. Ib qho ntxiv, Ph ntawv yuav tsum tsis txhob muab tso rau hauv nruab nrab ntawm nruab nrab lossis alkaline cov kev daws teeb meem, raws li ntev ntev hauv cov iav lub iav lav teb qeeb. Qhov raug npaj rau ntawm PH.Cauv: Siv ib pob ntawv ntawm PH 4.00 Buffer (250mL ntawm Kev Ntsuas Cov Tshuaj Ntsig, Ua kom txog thaum ua kom sov, thiab do kom txog thaum yaj tag nrho.
