MNDANDANDA WA ZOKHUDZA

Electro-oxidation (EO) ndi njira yomwe imagwiritsidwa ntchito poyeretsa madzi oyipa, makamaka otayira m'mafakitale. Ndi mtundu wa advanced oxidation process (AOP) womwe umaphatikizapo kugwiritsa ntchito gwero lakunja la mphamvu mu selo la electrochemical lomwe lili ndi ma elekitirodi amodzi kapena angapo. Njirayi imagwira ntchito popanga mitundu yolimba ya oxidizing pa anode, yomwe imagwirizana ndi zonyansa ndikuzichepetsa. The refractory mankhwala amasandulika reaction intermediate ndipo potsirizira pake kukhala madzi ndi CO2 kupyolera mu mineralization wathunthu.

Zofunikira za Electro-Oxidation:

Electrochemical Cell: Kukonzekera kumapangidwa ndi selo la electrochemical lomwe lili ndi maelekitirodi awiri, anode ndi cathode, olumikizidwa ku gwero la mphamvu.

Kupanga Mitundu ya Oxidizing: Pamene mphamvu yowonjezera ndi electrolyte yokwanira yothandizira imaperekedwa, mitundu yamphamvu ya oxidizing imapangidwira pamtunda wa anode, womwe umagwirizanitsa ndi zonyansa ndikuziwononga.

Hydroxyl Radicals: Ma Hydroxyl radicals (HO•) ndi ma hydroxyl radicals (HO•) omwe amatha kuchitapo kanthu ndi pafupifupi zowononga zonse ndikuwapangitsa kukhala CO2 ndi H2O mosasankha m'malo ozungulira komanso kutentha kwa mumlengalenga.

Zinthu za Anode: Zida za anode zimatha kusiyanasiyana malinga ndi momwe zimagwiritsidwira ntchito, ndi ma elekitirodi a diamondi a boron-doped (BDD) omwe amagwiritsidwa ntchito kwambiri popanga mitundu yotakasuka.

Zida za Cathode: Ma cathodes amapangidwa ndi mbale zachitsulo zosapanga dzimbiri, mauna a platinamu, kapena ma electrode a carbon.

Mwachangu: Electro-oxidation imatha kuthetsa zodetsa kudzera mu okosijeni wachindunji pa anode/aqueous solution interface komanso kudzera m'magulu opangidwa ndi anodically, monga mitundu ya okosijeni yokhazikika.

ubwino: Electro-oxidation sichifuna kuwonjezera mankhwala akunja, ndizosavuta kukhazikitsa, ndipo zimatha kuphatikizidwa ndi matekinoloje ena kuti akwaniritse miyezo yapamwamba yakuwonongeka ndikuchepetsa ndalama zogwirira ntchito.

Mapulogalamu: Electro-oxidation Zakhala zikugwiritsidwa ntchito pochiza zowononga zosiyanasiyana zowononga komanso zosawonongeka, kuphatikiza ma aromatics, mankhwala ophera tizilombo, mankhwala osokoneza bongo, ndi utoto.

Electro-oxidation ikuphatikizapo:madzi otayira disinfection ndi makutidwe ndi okosijeni anode,kuchotsa ammonia nayitrogeni anode,kuchotsa cod anode.
