Cov lus teb nyob ntawm tus qauv tsim electrode, dej zoo, kev ua haujlwm, thiab kev saib xyuas.
Phau ntawv qhia no piav qhia txog kev sib raug zoo ntawm titanium anodes, electrode scaling, thim rov qab polarity, thiab xaiv electrode.
1. Lub tshuab hluav taws xob Sodium Hypochlorite ua haujlwm li cas
Lub tshuab hluav taws xob sodium hypochlorite tsim cov tshuaj tua kab mob los ntawm electrolysis ntawm sodium chloride tov.
Nyob rau hauv lub electrolytic cell:
Hauv qhov anode:
2Cl⁻ → Cl₂ + 2e⁻
Chlorine yog generated thiab reacts nrog dej los tsim hypochlorous acid thiab hypochlorite.
Hauv cathode:
2H₂O + 2e⁻ → H₂ + 2OH⁻
Hydrogen thiab hydroxide ions raug tsim.
Qhov kev ua tau zoo ntawm lub tshuab hluav taws xob yog nyob ntawm:
