pH meter electrode lom ua rau
hais txog hom ndlwg Lub creation ntawm hluav taws xob raws nyob rau hauv ib tug pH meter electrode yog nyob ntawm lub electrolyte lub internal micro-osmotic siab, uas tso cai rau nws permeate lub ntsuas tshuaj. Thaum qhov nruab nrab muaj qhov siab siab lossis qhov siab, txoj kev hloov cov kua dej tsis zoo, muaj cov pa npuas, thiab lwm yam, qhov no tuaj yeem tiv thaiv cov electrolyte los ntawm kev xau thiab nce qhov hluav taws xob txoj kev nruab nrab impedance. Tus choj ntsev lossis txawm tias pH meter electrode yuav kis tau yog tias cov kua rov qab mus rau hauv nws. Nws tuaj yeem ua rau muaj cov tshuaj electrolyte lossis cov tshuaj lom hauv cov tshuaj lom neeg (xws li AgCl sulfide rau Ag2S).
Kev poob ntawm alkaline cov ntaub ntawv (feem ntau monovalent cations) nyob rau hauv ib tug rhiab iav daim nyias nyias nyob rau hauv ib tug muaj zog oxidizing xov xwm yuav ua mob rau lub hydration txheej thiab tshuaj lom cov electrode ntawm pH meter. Koj tuaj yeem xaiv pH meter electrode uas tuaj yeem tiv taus acid. Txoj kev tsim khoom siv cov txheej txheem tshwj xeeb ntawm kev tswj hwm (ib qho tshwj xeeb ntxiv ion mis) tau txhim kho cov iav zaj duab xis muaj peev xwm tiv taus acidosis. Lub linearity yog tsau.
Sab nraud ntawm pH2pH9, pH meter electrode tsis muaj kev sib raug zoo linear, thiab nws yog ib qho yooj yim rau ib tug loj tus naj npawb ntawm hydronium ions-H3O-los tsim nyob rau hauv cov kua qaub heev. Yog li ntawd, tus naj npawb ntawm H ntawm pH meter electrode nto ntog thiab pH tus nqi nce. Cov txheej txheem sib pauv ntawm cov hydrogen hauv cov tshuaj thiab cov hydrogen ntawm cov electrode hydration txheej kuj tseem koom nrog Na hauv qhov nruab nrab alkaline, ua rau cov electrode muaj peev xwm ntawm pH meter thiab txo qis pH.
