Dareen ballaadhan, oksidation-ka elektiroonigga ah waxa loola jeedaa dhammaan geeddi-socodka korantada, kaas oo ku lug leh fal-celinta elektiroonigga ah ee tooska ah ama aan tooska ahayn ee ka dhacaya korantada ee ku salaysan mabaadi'da falcelinta-yaraynta oksaydhka. Dareen-celintan waxay ujeeddadeedu tahay in la yareeyo ama laga saaro wasakhowga biyaha wasakhda ah.
Si cidhiidhi ah loo qeexay, oksaydheynta korantada ayaa si gaar ah u tixraacaysa habka anodic. Habkan, xal organic ama hakinta ayaa lagu soo bandhigay unug elektrolytic ah, iyo iyada oo loo marayo codsiga hadda tooska ah, electrons ayaa laga soo saaraa anode, taasoo keenta oksaydhka xeryahooda organic. Taas beddelkeeda, biraha-valence-ka hooseeya ayaa lagu oksijiin karaa ions birta-sare ee anode, ka dibna ka qaybqaata oksaydhka xeryahooda organic. Caadi ahaan, kooxo hawleed gaar ah oo ku jira xeryahooda organic waxay soo bandhigaan firfircoonida korantada. Iyada oo ay saameyn ku leedahay beerta korantada, qaab dhismeedka kooxahan shaqeynaya waxay ku dhacaan isbeddelo, beddelaan sifooyinka kiimikada ee xeryahooda organic, yaraynta suntooda, iyo kor u qaadida biodegradability.
oxidation Electrochemical waxa loo qaybin karaa laba nooc: oksaydhaynta tooska ah iyo oksaydhka tooska ah. oksaydhaynta tooska ah (electrolysis toos ah) waxa ay ku lug leedahay ka saarida tooska ah wasakhowga biyaha wasakhda ah iyada oo la ogaysiinayo electrode-ka. Nidaamkan waxaa ku jira hababka anodic iyo kathodic labadaba. Habka anodic-ku wuxuu ku lug leeyahay oksaydheynta wasakhowga dusha anode-ka, iyaga oo u beddelaya walxo sun ah oo yar ama walxo aad u badan oo noole, taas oo yaraynaysa ama tirtiraysa wasakhowga. Habka cathodic wuxuu ku lug leeyahay dhimista wasakhaha dusha sare ee cathode waxaana ugu horreyn loo isticmaalaa dhimista iyo ka saarista hydrocarbons halogenated iyo soo kabashada biraha culus.
Habka cathodic sidoo kale waxaa loo tixraaci karaa dhimista korantada kiimikada. Waxay ku lug leedahay wareejinta elektarooniga si loo yareeyo ions birta culus sida Cr6+ iyo Hg2+ ee gobolladooda hoose ee oksaydhka. Intaa waxaa dheer, waxay yareyn kartaa xeryahooda dabiiciga ah ee koloriin ku jira, iyaga oo u beddelaya walxo sun yar ama aan sun ahayn, ugu dambeyntiina waxay kor u qaadaan biodegradability-kooda:
R-Cl + H+ + e → RH + Cl-
oksaydhaynta aan tooska ahayn (electrolysis aan toos ahayn) waxa ay ku lug leedahay isticmaalka kimikalka kiimikaad ahaan loo soo saaray oksaydhaynta ama yaraynta wakiilada sidii fal-celin ama kicin si loogu badalo wasakhowga walxo sun yar. Electrolysis aan toos ahayn waxaa loo sii kala saari karaa habab dib loo rogi karo oo aan laga noqon karin. Nidaamyada dib-u-noqoshada ah (dhexdhexaadinta oksaydheynta korantada) waxay ku lug leedahay dib-u-cusboonaynta iyo dib-u-warshadaynta noocyada redox inta lagu jiro habka korantada. Hababka aan dib-u-noqon karin, dhanka kale, waxay adeegsadaan walxaha laga soo saaro fal-celinta elektiroonigga ah ee aan la soo celin karin, sida walxaha oksaydhiyeyaasha xooggan sida Cl2, chlorates, hypochlorites, H2O2, iyo O3, si ay u oksijiyeen xeryahooda organic. Nidaamyada aan dib-u-noqon karin ayaa sidoo kale dhalin kara dhexdhexaadin sare oo oksaydh ah, oo ay ku jiraan electrons-ka, · HO radicals, · HO2 radicals (hydroperoxyl radicals), iyo · O2-radicals (superoxide anions), kuwaas oo loo isticmaali karo hoos u dhigista iyo baabi'inta wasakhaha sida cyanide, phenols, COD (Baahida Ogsajiinta Kiimikada), iyo S2-ions, oo ugu dambeyntii u beddelaya walxaha aan waxyeello lahayn.
Marka laga hadlayo oksaydhka anodic-ka tooska ah, uruurinta falceliska hooseeya waxay xaddidi kartaa falcelinta dusha elektiroonigga ah sababtoo ah xaddidaadyada wareejinta tirada badan, halka xaddidani aysan ka jirin hababka oksaydhka tooska ah. Inta lagu jiro hababka oksaydheynta tooska ah iyo kuwa aan tooska ahayn labadaba, falcelinta dhinaca ah ee ku lug leh jiilka gaaska H2 ama O2 ayaa laga yaabaa inay dhacaan, laakiin falcelinta dhinacan ayaa lagu xakameyn karaa iyada oo loo marayo xulashada qalabka korantada iyo xakamaynta suurtagalka ah.
oksaydhaynta Electrochemical waxa la ogaaday in ay waxtar u leedahay daawaynta biyaha wasakhda ah oo leh ururo dabiici ah oo aad u sarreeya, isku dhafan isku dhafan, walxo badan oo dib u celin ah, iyo midab sare leh. Adigoo isticmaalaya anodes-ka leh dhaqdhaqaaqa kiimikaad ee elektiroonigga ah, tignoolajiyadani waxay si hufan u dhalin kartaa radicals hydroxyl oxidative. Nidaamkani wuxuu keenaa kala-goynta wasakhowga organic-ga ah ee joogtada ah oo noqda walxo aan sun ahayn, walxo biodegradable ah iyo macdano dhammaystiran oo ay ka mid yihiin xeryahooda sida carbon dioxide ama carbonates.
