Kayan aikin maganin ruwan sharar gida na Electro-Fenton sun dogara ne akan ƙa'idodin Fenton catalytic oxidation, wanda ke wakiltar wani ci gaba na tsarin oxidation da ake amfani da shi don lalata da kuma magance yawan tarin ruwa, guba, da kuma ruwan sharar gida na halitta.
Masanin kimiyyar Faransa Fenton ne ya ƙirƙiro hanyar reagent ta Fenton a shekarar 1894. Asalin amsawar reagent ta Fenton shine samar da catalytic na hydroxyl radicals (•OH) daga H2O2 a gaban Fe2+. Bincike kan fasahar electro-Fenton ya fara ne a shekarun 1980 a matsayin hanyar shawo kan iyakokin hanyoyin Fenton na gargajiya da kuma haɓaka ingancin maganin ruwa. Fasahar Electro-Fenton ta ƙunshi ci gaba da samar da Fe2+ da H2O2 ta hanyar hanyoyin lantarki, tare da amsawa nan take don samar da hydroxyl radicals masu aiki sosai, wanda ke haifar da lalacewar mahaɗan halitta.
Ainihin, yana samar da reagents na Fenton kai tsaye yayin aikin electrolysis. Babban ƙa'idar amsawar electro-Fenton shine narkar da iskar oxygen a saman wani abu mai dacewa na cathode, wanda ke haifar da samar da hydrogen peroxide (H2O2) na lantarki. Sannan H2O2 da aka samar zai iya amsawa tare da mai kara kuzari na Fe2+ a cikin maganin don samar da wani wakili mai ƙarfi na oxidizing, hydroxyl radicals (•OH), ta hanyar amsawar Fenton. An tabbatar da samar da •OH ta hanyar tsarin electro-Fenton ta hanyar gwaje-gwajen sinadarai da dabarun spectroscopic, kamar kamawa da juyawa. A aikace-aikace, ana amfani da ƙarfin oxidation mai ƙarfi na •OH don cire hadaddun kwayoyin halitta masu sake yin watsi da su yadda ya kamata.
O2 + 2H+ + 2e → H2O2;
H2O2 + Fe2+ → [Fe(OH)2]2+ → Fe3+ + •OH + OH-.
Fasahar Electro-Fenton ta fi amfani wajen magance leachate daga shara, ruwa mai tarin yawa, da kuma sharar masana'antu daga masana'antu kamar sinadarai, magunguna, magungunan kashe kwari, rini, yadi, da kuma electroplating. Ana iya amfani da shi tare da kayan aikin iskar shara na electrocatalytic don inganta lalacewar ruwan shara sosai yayin cire CODCr. Bugu da ƙari, ana amfani da shi don magance leachate daga shara, ruwa mai tarin yawa, da ruwan sharar masana'antu daga sinadarai, magunguna, magungunan kashe kwari, rini, yadi, electroplating, da sauransu, rage CODCr kai tsaye don cika ƙa'idodin fitarwa. Haka kuma ana iya haɗa shi da "kayan aikin electro-Fenton" don rage farashin aiki gaba ɗaya.
