Ikoranabuhanga rya Electro-Fenton

Ibikoresho byo gutunganya amazi y’amashanyarazi ya Electro-Fenton bishingiye cyane cyane ku mahame ya okiside ya Fenton catalitike, byerekana uburyo bwa okiside yateye imbere ikoreshwa mu kwangirika no gutunganya amazi y’amazi menshi, uburozi, n’amazi.

Uburyo bwa reagent bwa Fenton bwavumbuwe n’umuhanga w’umufaransa Fenton mu 1894.Icyerekezo cya reaction ya Fenton nigisekuru cya catalitiki ya hydroxyl radicals (• OH) kuva H2O2 imbere ya Fe2 +. Ubushakashatsi ku ikoranabuhanga rya electro-Fenton bwatangiye mu myaka ya za 1980 mu rwego rwo gutsinda imbogamizi z’uburyo gakondo bwa Fenton no kuzamura imikorere y’amazi. Ikoranabuhanga rya Electro-Fenton ririmo umusaruro uhoraho wa Fe2 + na H2O2 binyuze mu mashanyarazi, byombi bihita byitwara kubyara hydroxyl radicals ikora cyane, biganisha ku kwangirika kw’ibinyabuzima.

Byibanze, itanga reagent ya Fenton mugihe cya electrolysis. Ihame ryibanze ryibikorwa bya electro-Fenton nugusenyuka kwa ogisijeni hejuru yikintu cya cathode ikwiye, biganisha ku mashanyarazi ya hydrogène peroxide (H2O2). H2O2 yakozwe irashobora noneho gukora hamwe na catalizike ya Fe2 + mugisubizo kugirango itange imbaraga zikomeye za okiside, hydroxyl radicals (• OH), binyuze mubitekerezo bya Fenton. Umusaruro wa • OH ukoresheje inzira ya electro-Fenton byemejwe hakoreshejwe ibizamini bya chimique hamwe nubuhanga bwa spekitroscopique, nko gufata umutego. Mubikorwa bifatika, ubushobozi budahitamo imbaraga za okiside ya • OH ikoreshwa mugukuraho neza ibinyabuzima byongera imbaraga.

O2 + 2H + + 2e → H2O2;

H2O2 + Fe2 + → [Fe (OH) 2] 2+ → Fe3 + + • OH + OH-.

Ikoranabuhanga rya Electro-Fenton rirakoreshwa cyane cyane mugutegura imyanda iva mu myanda, amazi yibanze, hamwe n’amazi mabi y’inganda ava mu nganda nk’imiti, imiti, imiti yica udukoko, irangi, imyenda, hamwe n’amashanyarazi. Irashobora gukoreshwa ifatanije na electrocatalytic ibikoresho bigezweho bya okiside kugirango bitezimbere cyane ibinyabuzima byangiza amazi mabi mugihe ukuraho CODCr. Byongeye kandi, ikoreshwa mu kuvura byimbitse imyanda iva mu myanda, amazi yibanze, hamwe n’amazi mabi y’inganda ava mu miti, imiti, imiti yica udukoko, irangi, imyenda, amashanyarazi, nibindi, bigabanya CODCr kugirango yujuje ubuziranenge. Irashobora kandi guhuzwa n "ibikoresho bya electro-Fenton ibikoresho" kugirango igabanye ibikorwa rusange.
