Mfundo ya chithandizo cha ozoni pamadzi oipa:
Ozone ali ndi mphamvu yamphamvu kwambiri ya okosijeni.Pochiza madzi oyipa, mphamvu yamphamvu ya okosijeni ya ozone imagwiritsidwa ntchito.Pambuyo pa chithandizo ndi ozoni, palibe kuipitsidwa kwachiwiri kapena mankhwala owopsa.Zomwe zimachitika pakati pa ozoni ndi madzi onyansa ndizovuta kwambiri ndipo zimaphatikizapo njira zotsatirazi: choyamba, mamolekyu a mpweya wa ozone amasiyana kuchokera ku gawo la mpweya kupita kumadera osakanikirana.Ndiye, pamene ndende ya reactants mu magawo awiri kufika mlingo pafupifupi pa mawonekedwe, iwo amapereka mkhalidwe wa thupi ofanana;pambuyo pake, ozoni idzafalikira kuchokera kudera lapakati kupita ku gawo lamadzimadzi ndikukumana ndi mankhwala.
Kufalikira kwa zinthu zomwe zimachitika kumayambika kutengera kuchuluka kwa ndende.Pansi pa zochitika zosiyanasiyana za biochemical ndi physicochemical, ozoni imatha kusintha zinthu zokhala ndi mamolekyu olemera kwambiri m'madzi otayidwa kukhala zinthu zocheperako ndikusintha zinthu zosagwira ntchito kukhala zotakataka.Chifukwa chake, ozoni sachepetsa kwambiri zinthu zachilengedwe m'madzi otayidwa, koma amatha kugwiritsa ntchito mphamvu yake yamphamvu ya okosijeni kuti asinthe mawonekedwe ndi zinthu zoipitsa zachilengedwe, ndikusintha zinthu zovuta kutsitsa kapena kuwononga nthawi yayitali kukhala zinthu zazing'onoting'ono zomwe zimatha oxidizable. .
Mfundo yakuchiritsa kwa ozoni m'madzi onyansa makamaka imadalira mamolekyu a ozone ndi ma hydroxyl radicals omwe amapangidwa mumadzi ake kuti awononge zinthu zonunkhira monga phenol, toluene, ndi benzene.Njira yochiritsira imatha kutheka ndi njira ziwiri.
Njira yoyamba ndi Direct oxidation.Chifukwa cha nucleophilic ndi electrophilic properties, ozoni amatha kuchitapo kanthu mosavuta ndi zinthu zamoyo m'madzi otayira, kumenyana ndi magulu ogwira ntchito a zowononga monga phenols ndi anilines, ndikupanga ma asidi owonongeka.
Njira yachiwiri imakhudzanso kutulutsa kwamphamvu kwa ma hydroxyl radicals kuchokera ku mamolekyu a O3, kuyambitsa njira yolumikizirana yomwe imakwaniritsa mosadukiza makutidwe ndi okosijeni ndi kuwonongeka kwa mitundu yosiyanasiyana ya zoipitsa zachilengedwe, ndikukwaniritsa kuthira madzi onyansa m'mafakitale.
Kutengera maphunziro am'mbuyomu, chithandizo cha ozoni chimadalira kwambiri mamolekyu a ozoni ndi ma hydroxyl radicals opangidwa mumadzi ake kuti awononge zinthu zonunkhira monga phenol, toluene, ndi benzene.Choncho, pali njira ziwiri za mankhwala: mwachindunji makutidwe ndi okosijeni, amene amapezerapo mwayi nucleophilic ndi electrophilic katundu ozoni kuyambitsa anachita ndi zoipitsa ndi kupanga biodegradable zidulo, ndi osalunjika makutidwe ndi okosijeni, zomwe zikuphatikizapo chothandizira m'badwo wa hydroxyl ankafuna kusintha zinthu mopitirira kuchokera O3 mamolekyu kuti oxidize. ndi kuchepetsa kukula kwa organic zoipitsa, kukwaniritsa chithandizo chamankhwala otayidwa mafakitale mafakitale.
Ntchito zenizeni za ma jenereta a ozone pakuwongolera madzi oyipa zimaphatikizapo nthambi zingapo zothirira madzi oyipa monga zinyalala zapakhomo, zotsukira zinyalala, madzi otayira m'mafakitale, madzi onyansa achilengedwe, kusindikiza nsalu ndi utoto wamadzi onyansa, madzi otayira azachipatala, madzi onyansa am'madzi, madzi onyansa okhala ndi phenol, madzi onyansa opangira mapepala, Kutentha madzi oyipa, chakudya fakitale madzi zinyalala, mankhwala fakitale otayira, etc.
Pankhani ya chithandizo chamadzi, majenereta a ozoni angagwiritsidwenso ntchito pochiza madzi oyeretsedwa, malo ochizira madzi apampopi, mafakitale akumwa, madzi akumwa, madzi amchere, madzi okonzedwa kuti azigulitsa chakudya, madzi a m'chipatala, madzi abwino, madzi apamtunda, madzi achiwiri, ndi madzi osinthidwanso.
