Munguva pfupi yapfuura, boka rekutsvakurudza raProfessor Kong Lingtao kubva kuHefei Institute of Physics, Chinese Academy of Sciences yakagadzirira amorphous Co/C composite zvinhu zve activating hydrogen peroxide (H2O2) kuti ibudise singlet oxygen uye nekuona kusarudzwa kwe oxytetracycline (OTC) yakaoma kunzwisisa. matrices emvura. Kubvisa bonde.Zvabuda zvakatsikiswa mujenari Chemical Engineering.googletag.cmd.push(function() {googletag.display('div-gpt-ad-1449240174198-2'); });
OTC ndiyo inonyanyozivikanwa yetetracycline mishonga inorwisa mabhakitiriya mukuchengeta mhuka.Inogona kuonekwa munzvimbo dzine kugadzikana kwakasimba kwehupenyu, zvakadai semvura nevhu, zvisingagoni kubviswa zvinobudirira nenzira dzemazuva ose dzounyanzvi.
Seyakareruka uye inoshanda yepamusoro oxidation tekinoroji, Fenton-yakafanana oxidation inoonekwa senzira inoshanda yekudzora kusvibiswa kwemvura.Se electrophilic isiri-radical, singlet oxygen inoratidzira yakanakisa anti-kupindira kugona kumashure kwe substrates, iyo inobatsira pakubvisa kwakasarudzika. yezvakasvibiswa zvakasvibiswa zvine mapoka e-electron-rich.Zvisinei, mune zvakawanda zveFenton-like reactions, chibereko che singlet oxygen chakaderera uye mupiro wacho muduku.
Muchidzidzo ichi, vatsvakurudzi vakagadzira uye vakagadzira hollow amorphous Co/C composite ine nhamba huru yeokisijeni-ine mapoka anoshanda akadai se carbonyl uye hydroxyl mapoka akagoverwa pamusoro.
Vakawana zvinhu zveCo/C-3 kuburikidza nekugadzirisa chiyero checobalt nekabhoni, uye vakawana kuderedzwa kwakanyanya kwe20 ppm OTC nekuita H2O2 panguva isina kwayakarerekera pH. mhedzisiro yekudzima kuyedza uye erekitironi paramagnetic resonance yakasimbisa kuti iyo yakashandurwa singlet okisijeni ndiyo yaive huru oxidizing mhando, uye hapana hydroxyl radical. yakaonekwa muhurongwa.
Kubatana pakati pecobalt neoksijeni-ine mapoka anoshanda mukati mezvinyorwa zvinoita basa rinokosha pakuita hydrogen peroxide mukuumbwa kwe singlet oxygen.Kuwedzera, nzira dzinogona kuparara uye zvinogona kuitika ecotoxicity yeOTC uye yepakati yayo yakaratidzwa zvakare.
