Vuba aha, itsinda ry’ubushakashatsi bwa Porofeseri Kong Lingtao wo mu Ishuri Rikuru ry’Ubugenge rya Hefei, Ishuri Rikuru ry’Ubumenyi ry’Ubushinwa ryateguye ibikoresho bitagira ingano bya amorphous Co / C byo gukoresha hydrogène peroxide (H2O2) kugira ngo bibyare ogisijeni imwe kandi bamenye guhitamo oxytetracycline (OTC) mu kigo matrices. Kurandura imibonano mpuzabitsina. Ibisubizo byatangajwe mu kinyamakuru Chemical Engineering.googletag.cmd.push (imikorere () {googletag.display ('div-gpt-ad-1449240174198-2');});
OTC ni antibiyotike ya tetracycline ikunze kugaragara cyane mu bworozi.Bishobora kugaragara ahantu hafite umutekano muke w’ibinyabuzima, nk'amazi n'ubutaka, bidashobora gukurwaho neza hakoreshejwe uburyo bwa tekiniki busanzwe.
Nka tekinoroji yoroshye kandi ikora neza ya okiside, okiside isa na Fenton ifatwa nkuburyo bwiza bwo kurwanya umwanda w’amazi.Nkuko electrophilique idafite radical, ogisijeni imwe rukumbi igaragaza ubushobozi buhebuje bwo kurwanya kwivanga kuri substrate yinyuma, ifasha mugukuraho guhitamo y’imyanda ihumanya irimo amatsinda akungahaye kuri electron.Nyamara, mubitekerezo byinshi bisa na Fenton, umusaruro wa ogisijeni umwe rukumbi ni muto kandi umusanzu ni muto.
Muri ubu bushakashatsi, abashakashatsi bashushanyije kandi bahimba amorphous Co / C yuzuye hamwe numubare munini wa ogisijeni urimo amatsinda akora nka karubone na hydroxyl matsinda yatanzwe hejuru.
Babonye ibikoresho bya Co / C-3 mugutezimbere igipimo cya cobalt na karubone, kandi bagera ku iyangirika ryiza rya 20 ppm OTC bakoresheje H2O2 kuri pH idafite aho ibogamiye. Sisitemu yo kwangirika kwa catalitike yerekana uburyo bwiza bwo gusubiramo, gutuza no kurwanya kwivanga. ibyavuye mu bushakashatsi bwo kuzimya hamwe na electron paramagnetic resonance yemeje ko ogisijeni yahinduwe imwe mu moko nyamukuru ya okiside, kandi nta hydroxyl radical yagaragaye muri sisitemu.
Imikoranire hagati ya cobalt na ogisijeni irimo amatsinda akora mu bikoresho bigira uruhare runini mu gukora hydrogène peroxide mu gukora ogisijeni imwe rukumbi. Byongeye kandi, inzira zishobora gutesha agaciro ndetse n’ibishobora kuba byangiza ibidukikije bya OTC n’abunzi bayo.
Nyamuneka koresha iyi fomu niba uhuye namakosa yimyandikire, adahwitse, cyangwa ushaka kohereza icyifuzo cyubwanditsi kubikubiye kururu rupapuro.

Uru rubuga rukoresha kuki kugirango rufashe kugendagenda, gusesengura imikoreshereze ya serivisi zacu, gukusanya amakuru yo kumenyekanisha ibikorwa byihariye, no gutanga ibikubiye mu bandi bantu. Ukoresheje urubuga rwacu, wemera ko wasomye kandi wunvise Politiki y’ibanga n'amabwiriza agenga imikoreshereze.
