Cov txheej txheem ntawm electrolyzing ib brine tov siv titanium electrodes los tsim chlorine feem ntau hu ua "electrolysis ntawm brine." Nyob rau hauv cov txheej txheem no, titanium electrodes yog ua hauj lwm los pab txhawb oxidation cov tshuaj tiv thaiv ntawm chloride ions nyob rau hauv lub brine, ua rau lub tsim ntawm chlorine gas. Tag nrho cov tshuaj sib npaug rau cov tshuaj tiv thaiv yog raws li nram no:
Hauv qhov sib npaug no, chloride ions raug oxidation ntawm lub anode, uas ua rau cov roj chlorine ntau lawm, thaum cov dej molecules raug txo qis ntawm cathode, yielding hydrogen gas. Tsis tas li ntawd, hydroxide ions raug txo qis ntawm lub anode, tsim cov roj hydrogen thiab sodium hydroxide.
Kev xaiv ntawm titanium electrodes yog vim titanium zoo heev corrosion kuj thiab conductivity, cia nws mus rau cov tshuaj tiv thaiv stably thaum electrolysis tsis muaj corrosion. Qhov no ua rau titanium electrodes yog qhov kev xaiv zoo tshaj plaws rau electrolysis ntawm brine.
Lub electrolysis ntawm saline dej feem ntau xav tau ib qho hluav taws xob sab nraud los muab lub zog rau cov tshuaj tiv thaiv electrolytic. Lub zog hluav taws xob no feem ntau yog cov khoom siv hluav taws xob ncaj qha (DC) vim tias cov tshuaj tiv thaiv electrolytic yuav tsum muaj kev coj ua zoo ib yam ntawm cov dej ntws tam sim no, thiab DC fais fab mov tuaj yeem xa cov kev taw qhia tam sim no.
Hauv cov txheej txheem ntawm electrolyzing dej saline los tsim cov roj chlorine, ib qho hluav taws xob qis DC feem ntau ua haujlwm. Qhov voltage ntawm lub hwj chim mov yog nyob ntawm tej yam kev mob tshwm sim thiab cov khoom tsim, tab sis feem ntau yog nyob ntawm 2 mus rau 4 volts. Tsis tas li ntawd, qhov kev siv hluav taws xob tam sim no yog qhov tseem ceeb heev uas yuav tsum tau txiav txim siab raws li qhov loj ntawm cov tshuaj tiv thaiv chamber thiab cov khoom xav tau.
Hauv cov ntsiab lus, qhov kev xaiv ntawm lub hwj huam mov rau electrolysis ntawm saline dej nyob ntawm seb cov kev cai tshwj xeeb ntawm kev sim lossis cov txheej txheem kev lag luam los xyuas kom meej cov tshuaj tiv thaiv zoo thiab kev ua tiav ntawm cov khoom xav tau.
