ʻO ka hoʻohaʻahaʻa koho ʻana o ka oxytetracycline e ka oxygen singlet i loko o kahi oxidation like me Fenton

I kēia mau lā, ua hoʻomākaukau ka pūʻulu noiʻi a Professor Kong Lingtao mai ka Hefei Institute of Physics, Chinese Academy of Science i kahi mea hollow amorphous Co/C composite no ka hoʻoulu ʻana i ka hydrogen peroxide (H2O2) e hoʻohua i ka oxygen singlet a hoʻomaopopo i ke koho ʻana o ka oxytetracycline (OTC) i loko o ka paʻakikī. wai matrices. Hoʻopau moe kolohe. Ua paʻi ʻia nā hopena i loko o ka puke pai Chemical Engineering.googletag.cmd.push(function() {googletag.display('div-gpt-ad-1449240174198-2');});
ʻO ka OTC ka lāʻau'alopelo tetracycline maʻamau i ka mahiʻai holoholona. Hiki ke ʻike ʻia ma nā wahi me ke kūpaʻa olaola ikaika, e like me ka wai a me ka lepo, ʻaʻole hiki ke wehe pono ʻia e nā ʻano loea maʻamau.
Ma ke ʻano he ʻenehana oxidation maʻalahi a maikaʻi hoʻi, ua manaʻo ʻia ʻo Fenton-like oxidation ma ke ʻano he ala kūpono no ka mālama ʻana i ka pollution wai. o nā mea haumia organik i loaʻa nā pūʻulu waiwai electron. Akā naʻe, ma ka hapa nui o nā hopena like me Fenton, haʻahaʻa ka hua o ka oxygen singlet a liʻiliʻi ka haʻawina.
I loko o kēia noiʻi, ua hoʻolālā a hana nā mea noiʻi i kahi hollow amorphous Co/C composite me ka nui o nā pūʻulu hana o ka oxygen e like me ka carbonyl a me nā pūʻulu hydroxyl i māhele ʻia ma ka ʻili.
Ua loaʻa iā lākou ka mea Co/C-3 ma o ka hoʻonui ʻana i ka lakene o ka cobalt a me ke kalapona, a loaʻa i ka degradation maikaʻi loa o 20 ppm OTC ma ka hoʻoulu ʻana i ka H2O2 ma ka pH neutral. ʻO nā hopena o nā hoʻokolohua kinai ʻana a me ka electron paramagnetic resonance i hōʻoia ʻia ʻo ka oxygen singlet i hoʻololi ʻia ʻo ia ke ʻano mea hoʻokahe nui, a ʻaʻohe hydroxyl radical i ʻike ʻia i loko. ka ʻōnaehana.
ʻO ka synergy ma waena o ka cobalt a me ka oxygen i loko o nā pūʻulu hana i loko o ka mea hana i ka hana nui i ka hoʻoulu ʻana i ka hydrogen peroxide i ka hoʻokumu ʻana o ka oxygen singlet.
E ʻoluʻolu e hoʻohana i kēia palapala inā ʻike ʻoe i nā hewa o ka ʻōlelo ʻana, nā hemahema, a i ʻole makemake e hoʻouna i kahi noi hoʻoponopono no ka ʻike o kēia ʻaoʻao. nā alakaʻi).
He mea nui kāu manaʻo manaʻo iā mākou. Akā naʻe, ma muli o ka nui o nā memo, ʻaʻole mākou e hōʻoiaʻiʻo i nā pane pākahi.
Hoʻohana wale ʻia kāu leka uila e hōʻike i ka poʻe i loaʻa i ka leka uila. ʻano.
E kiʻi i nā mea hou i kēlā me kēia pule a/a i kēlā me kēia lā i hoʻouna ʻia i kāu pahu pahu. Hiki iā ʻoe ke wehe i ka inoa i kēlā me kēia manawa a ʻaʻole loa mākou e kaʻana like i kāu kikoʻī me nā poʻe ʻekolu.
Ke hoʻohana nei kēia pūnaewele i nā kuki e kōkua i ka hoʻokele ʻana, hoʻopaʻa ʻia i kāu hoʻohana ʻana i kā mākou lawelawe, hōʻiliʻili i ka ʻikepili no ka hoʻolaha pilikino, a lawelawe i nā ʻike mai nā ʻaoʻao ʻekolu.
