Lisebelisoa tsa ho hloekisa metsi a litšila tsa Electro-Fenton li thehiloe haholo-holo holim'a melao-motheo ea Fenton catalytic oxidation, e emelang mokhoa o tsoetseng pele oa oxidation o sebelisetsoang ho senya le ho phekola metsi a litšila a mangata, a chefo le a tlhaho.
Mokhoa oa Fenton reagent o qapiloe ke rasaense oa Lefora Fenton ka 1894. Mohloli oa Fenton reagent reaction ke catalytic generation ea hydroxyl radicals (•OH) ho tloha H2O2 ka pel'a Fe2 +. Patlisiso mabapi le theknoloji ea electro-Fenton e qalile lilemong tsa bo-1980 e le mokhoa oa ho hlola mefokolo ea mekhoa ea setso ea Fenton le ho ntlafatsa ts'ebetso ea kalafo ea metsi. Theknoloji ea Electro-Fenton e kenyelletsa tlhahiso e tsoelang pele ea Fe2 + le H2O2 ka mekhoa ea electrochemical, ka bobeli ba arabela hang-hang ho hlahisa li-radicals tse sebetsang haholo tsa hydroxyl, tse lebisang ho senyeha ha metsoako ea tlhaho.
Ha e le hantle, e hlahisa li-reagents tsa Fenton ka kotloloho nakong ea ts'ebetso ea electrolysis. Molao-motheo oa motheo oa karabelo ea electro-Fenton ke ho qhibiliha ha oksijene holim'a thepa e loketseng ea cathode, e lebisang ho tlhahiso ea electrochemical ea hydrogen peroxide (H2O2). H2O2 e hlahisoang e ka khona ho itšoara ka Fe2 + catalyst ka tharollo ea ho hlahisa motsoako o matla oa oxidizing, hydroxyl radicals (• OH), ka mokhoa oa Fenton. Tlhahiso ea • OH ka ts'ebetso ea electro-Fenton e tiisitsoe ka liteko tsa lik'hemik'hale tsa lik'hemik'hale le mekhoa ea spectroscopic, e kang spin trapping. Lits'ebetsong tse sebetsang, bokhoni bo matla ba oxidation bo sa khethoeng ba • OH bo sebelisoa hampe ho tlosa metsoako ea tlhaho ea recalcitrant.
O2 + 2H+ + 2e → H2O2;
H2O2 + Fe2+ → [Fe(OH)2]2+ → Fe3+ + •OH + OH-.
Theknoloji ea Electro-Fenton e sebetsa haholo ho lokiseng leachate ho tsoa moo ho qhalloang mobu, lino tse nang le metsi a mangata, le metsi a litšila a indasteri a tsoang liindastering tse kang lik'hemik'hale, meriana, chefo e bolaeang likokoanyana, ho daea, masela le electroplating. E ka sebelisoa hammoho le lisebelisoa tsa electrocatalytic advanced oxidation ho ntlafatsa haholo biodegradability ea metsi a litšila ha o ntse o tlosa CODCr. Ho feta moo, e sebelisoa bakeng sa kalafo e tebileng ea leachate e tsoang moo ho qhalloang mobu, lino tse nang le metsi a mangata, le metsi a litšila a indasteri ho tsoa ho lik'hemik'hale, meriana, chefo e bolaeang likokoanyana, ho daea, masela, electroplating, joalo-joalo, ho fokotsa CODCr ka kotloloho ho fihlela litekanyetso tsa ho tsoa. E ka boela ea kopanngoa le "sesebelisoa sa "pulsed electro-Fenton" ho fokotsa litšenyehelo tsa ts'ebetso ka kakaretso.
