Tsis ntev los no, xib fwb Kong Lingtao cov kev tshawb fawb pab pawg los ntawm Hefei lub koom haum ntawm Physics, Suav Academy ntawm Sciences tau npaj ib tug hollow amorphous Co/C composite khoom rau activating hydrogen peroxide (H2O2) los tsim singlet oxygen thiab paub txog kev xaiv oxytetracycline (OTC) nyob rau hauv complex. dej matrices. Kev tshem tawm kev sib deev.Cov txiaj ntsig tau luam tawm hauv phau ntawv Journal Chemical Engineering.googletag.cmd.push(function() { googletag.display('div-gpt-ad-1449240174198-2'); });
OTC yog cov tshuaj tua kab mob tetracycline ntau tshaj plaws hauv kev yug tsiaj.Nws tuaj yeem kuaj pom hauv thaj chaw uas muaj zog lom neeg ruaj khov, xws li dej thiab av, uas tsis tuaj yeem raug tshem tawm zoo los ntawm cov txheej txheem txheej txheem.
Raws li ib qho yooj yim thiab ua tau zoo tshaj oxidation technology, Fenton-zoo li oxidation yog suav hais tias yog ib txoj kev zoo rau dej paug tswj.As ib tug electrophilic non-radical, singlet oxygen exhibits zoo heev los tiv thaiv kev cuam tshuam muaj peev xwm rau keeb kwm substrates, uas yog pab tau rau cov xaiv tshem tawm. ntawm cov organic pollutants uas muaj electron-nplua nuj pawg.Txawm li cas los xij, nyob rau hauv feem ntau Fenton-zoo li cov tshuaj tiv thaiv, cov tawm los ntawm singlet oxygen yog tsawg thiab cov kev pab yog me me.
Hauv txoj kev tshawb no, cov kws tshawb fawb tau tsim thiab tsim cov hollow amorphous Co/C composite nrog ntau cov pa oxygen uas muaj cov pab pawg xws li carbonyl thiab hydroxyl pawg faib rau saum npoo.
Lawv tau txais cov khoom siv Co/C-3 los ntawm optimizing qhov piv ntawm cobalt thiab carbon, thiab ua tiav qhov zoo tshaj plaws degradation ntawm 20 ppm OTC los ntawm activating H2O2 ntawm nruab nrab pH.The catalytic degradation system exhibits zoo heev repeatability, stability thiab anti-interference muaj peev xwm. Cov txiaj ntsig ntawm quenching thwmsim thiab electron paramagnetic resonance tau lees paub tias qhov hloov pauv singlet oxygen yog hom oxidizing tseem ceeb, thiab tsis muaj hydroxyl. radical tshwm nyob rau hauv lub system.
Kev sib koom ua ke ntawm cobalt thiab cov pa oxygen uas muaj cov pab pawg ua haujlwm hauv cov khoom siv ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj hydrogen peroxide hauv kev tsim cov pa oxygen. Ntxiv rau, txoj hauv kev ua kom degradation thiab muaj peev xwm ecotoxicity ntawm OTC thiab nws cov intermediates kuj tau tshwm sim.
