Posachedwapa, gulu kafukufuku Professor Kong Lingtao ku Hefei Institute of Physics, Chinese Academy of Sciences wakonza dzenje amorphous Co/C gulu zinthu kuti activating hydrogen peroxide (H2O2) kupanga singlet mpweya ndi kuzindikira kusankha oxytetracycline (OTC) mu zovuta. madzi matrices. Kuthetsa kugonana.Zotsatirazo zidasindikizidwa mu nyuzipepala Chemical Engineering.googletag.cmd.push(function() {googletag.display('div-gpt-ad-1449240174198-2'); });
OTC ndi mankhwala odziwika bwino a tetracycline poweta ziweto. Amatha kudziwika m'madera omwe ali ndi kukhazikika kwachilengedwe, monga madzi ndi nthaka, zomwe sizingachotsedwe bwino ndi njira zamakono.
Monga luso losavuta komanso logwira mtima la oxidation, Fenton-ngati oxidation imatengedwa ngati njira yabwino yothetsera kuwononga madzi. za zowononga organic zomwe zili ndi magulu olemera a electron.Komabe, muzochitika zambiri za Fenton, zokolola za singlet oxygen ndizochepa ndipo choperekacho ndi chochepa.
Mu kafukufukuyu, ochita kafukufuku adapanga ndikupanga gulu lopanda kanthu la amorphous Co / C lomwe lili ndi magulu ambiri ogwira ntchito okhala ndi okosijeni monga magulu a carbonyl ndi hydroxyl omwe amagawidwa pamwamba.
Adapeza zinthu za Co/C-3 pokulitsa chiŵerengero cha cobalt ndi kaboni, ndipo adapeza kuwonongeka kwabwino kwa 20 ppm OTC mwa kuyambitsa H2O2 pa pH ya ndale. Zotsatira za kuyesa kozimitsa ndi ma electron paramagnetic resonance zatsimikizira kuti mpweya wosinthika wa singlet ndiye mtundu waukulu wa okosijeni, ndipo palibe hydroxyl radical. adawonekera mu dongosolo.
Kugwirizana pakati pa cobalt ndi magulu ogwira ntchito omwe ali ndi okosijeni mkati mwazinthuzi kumagwira ntchito yofunika kwambiri poyambitsa hydrogen peroxide popanga singlet oxygen.
Chonde gwiritsani ntchito fomuyi ngati mukukumana ndi zolakwika za kalembedwe, zolakwika, kapena mukufuna kutumiza pempho la mkonzi pazomwe zili patsambali.Pazofunsa zambiri, chonde gwiritsani ntchito fomu yathu yolumikizirana.Kuti mumve zambiri, chonde gwiritsani ntchito gawo lomwe lili pansipa (chonde tsatirani. malangizo).
Ndemanga zanu ndi zofunika kwa ife.
Adilesi yanu ya imelo imagwiritsidwa ntchito podziwitsa omwe akulandirani omwe adatumiza imeloyo. Adilesi yanu kapena adilesi ya wolandila sizidzagwiritsidwa ntchito pazifukwa zina zilizonse. Zomwe mungalembe zizipezeka mu imelo yanu ndipo sizidzasungidwa ndi Phys.org m'njira iliyonse. mawonekedwe.
Pezani zosintha zamlungu ndi mlungu ndi/kapena zatsiku ndi tsiku kubokosi lanu lamakalata. Mutha kudziletsa nthawi iliyonse ndipo sitidzagawana zambiri ndi anthu ena.
Webusaitiyi imagwiritsa ntchito makeke kuti ikuthandizeni kuyenda, kusanthula momwe mumagwiritsira ntchito ntchito zathu, kusonkhanitsa deta kuti musatsatse makonda anu, ndikupereka zinthu zochokera kwa anthu ena. Pogwiritsa ntchito tsamba lathu, mumavomereza kuti mwawerenga ndikumvetsetsa Mfundo Zazinsinsi ndi Migwirizano yathu.
