Lead Dioxide Titanium Electrode
Nyob rau hauv ib puag ncig ntawm oxygen evolution, tib neeg tau tsim cov hlau lead dioxide electrode (PbO2): ib qho chaw tsis muaj stoichiometric uas tsis muaj oxygen thiab muaj cov hlau lead ntau dhau. Nws muaj ntau hom siv lead ua, siv cov anode electrodeposition los tsim cov -PbO2, uas muaj Oxidation, corrosion kuj (siab stability nyob rau hauv muaj zog acid H2S04 los yog HN03), siab oxygen overpotential, zoo hluav taws xob conductivity, muaj zog binding quab yuam, muaj zog oxidation muaj peev xwm thaum electrolyzed. nyob rau hauv aqueous tov, yuav dais loj tam sim no, thiab lwm yam.
Khoom Taw qhia
Cov hlau lead dioxide npog titanium anode (Ti-PbO2) muaj qhov tsis muaj zog, cov khoom siv hluavtaws ruaj khov, cov khoom oxidation tiv thaiv (cov khoom muaj peev xwm oxidation thaum lub sij hawm electrolysis hauv cov kua dej); Kev tawm tsam ntau dua (kev cia siab dua hauv cov khoom corrosive HzS04 lossis HN03).
PbO2 electrodeposition yog thawj zaug cov pa oxygen xws li chemisorbed OHads yuav tsim cov txheej txheem nruab nrab, tom qab ntawd tsim cov khoom nruab nrab ntawm cov khoom lag luam xws li Pb (OH) 2+, thiab thaum kawg oxidizes los tsim PbO2 txheej. Cov txheej txheem tshuaj tiv thaiv yog: lead dioxide anode
H2O → OHads + H ++ e−
Pb2 ++ OHads → Pb (OH) 2+
Pb (OH) 2 ++ H2O → PbO2 + 3H ++ e−
Musiani et al. Sau qhov sib npaug ntawm anodization nyob rau hauv ib qho kev daws ntawm tshem tawm cov hlau ions:
Mn ++ particles-me → MO (m + n) / 2-matrix
Khoom specifications:
zuag qhia tag nrho specifications: 5 * 1280 * 1380MM / coated titanium mesh cheeb tsam: 5 * 800 * 1280mm los yog ua raws li drawings
Txheej thickness: 3-5mm
Superior kev ua tau zoo:
1) Muaj peev xwm oxygen evolution: 1.68V
2) Kev ua haujlwm siab tam sim no: Max 5000A / M2
3) High efficiency efficiency
4) Ib qho yooj yim installation
5) Lub neej ntev: 3-5 xyoo
Qhov chaw thov:
1. Chrome plating hauv cov kua qaub nyuaj xws li chromic acid, tawv chromium plating, thiab siv cov hlau tsis muaj tin hauv kev lag luam steel.
2. Kev kho mob chromate. Kev kho deg ntawm cov hlau phaj thiab chromate kho cov khoom hlau.
3. Electrolytic zus tau tej cov inorganic tebchaw xws li chromic acid, perchlorate thiab periodate. Cov txheej txheem electrolytic oxidation yog siv los ntxuav cov dej khib nyiab kom ua rau cov tshuaj lom neeg oxygen xav tau (COD) thiab cov khoom siv oxygen (BOD) ncav cuag tus qauv tso tawm.
4. Electrolytic oxidation rau synthesize organic tebchaw nyob rau hauv pickling electrolysis.
5. Electrolytic zus tau tej cov ozone yuav tsum tau siv cov khoom siv electrode uas muaj cov pa oxygen ntau dhau. Cov hlau lead dioxide titanium electrode muaj kev ua haujlwm zoo catalytic.
6. Electrolyte rov qab thiab rho tawm ntawm cov hlau tsis muaj hlau hauv cov tshuaj acidic.
7. Kev kho dej khib nyiab. COD thiab BOD yog purified los ntawm electrolytic oxidation.
8. thawj qib tooj liab tshem tawm;
9. Rau hydrometallurgy ( rho tawm cov hlau muaj nuj nqis xws li npib tsib xee, tooj liab, cobalt, thiab lwm yam)
