Nrog rau cov teeb meem paug paug paug, xws li cov organic dyes thiab cov khoom siv saib xyuas tus kheej (ppcps) Cov kuab paug no ua rau muaj kev hem thawj loj rau ob hom kev noj qab haus huv thiab tib neeg kev noj qab haus huv, ua rau kev txhim kho dej haus dej tshwj xeeb tshaj yog ib qho tseem ceeb. Cov tshuaj ntsuab hnyav thev naus laus zis siv rau kev siv dej zam rau kev kho kom muaj kuab lom, muaj peev xwm muaj kuab lom los ntawm cov pa paug. Txawm li cas los xij, vim muaj lub pore loj loj ntawm cov kua mis muaj zog qis, lawv tawm tsam kom tau txais txiaj ntsig cov pa me me molecular orgeic.
Hauv cov ntsiab lus no, carbon nanotube (CNT) thev naus laus zis tau tawm los ua kev daws teeb meem. Cov Nanotubes, nrog lawv thaj chaw loj tshwj xeeb thaj av thiab adsorption zoo tshaj plaws, yog cov ntaub ntawv zoo tshaj plaws rau kev tshem cov pa roj me me orgeic. Txawm hais tias CNTs muaj cov kev tsis zoo hauv cov kev daws teeb meem a agglomerate, tsis yog kev sib cav ua haujlwm tau txhim kho lawv cov kev faib tawm thiab txhim kho lawv qhov muaj peev xwm adsorption. Los ntawm tsis-sib yeem ua haujlwm CNTs, cov kws tshawb nrhiav tsis tuaj yeem txhim kho kev kho mob dej tab sis kuj tsis muaj kev phom sij ecological posed los ntawm kev tso cov CNTs rau hauv ib puag ncig.
Cov kev tshawb fawb tau pom tias cov tshuaj zoo li nws zoo li cov tshuaj acid (ha), sodium dydraulic sulecyl sulecyl sulecyl sulecyl sulecyl sulecyl sulecyl sulecyl Cov tswv yim no hloov cov khoom saum npoo ntawm CNTs, txhim kho lawv cov dispersion thiab adsorption muaj peev xwm hauv cov kua aqueous. Ua haujlwm CNTsalized yog tom qab ntawd siv los ua kom cov roj qis-siab, uas txhim kho qhov ua tau zoo hauv kev tshem me me molecular airutants.
Kev tshawb fawb qhia tau tias cov ua haujlwm tau zoo ntawm cov neeg muaj peev xwm ua tau zoo tshem tawm cov cim cationic thiab anionic dyes, nrog rau ppcps, thaum lub sijhawm lim dej. Txawv ntau hom CNTs, xws li mwcnt-booh, thiab swcnt-cooh, thiab swcnt, qhia sib txawv ntawm cov khoom sib txawv rau cov kuab paug txawv txav. Piv txwv li, MWCNT cov mem tes tau ua tau zoo tshaj plaws ntawm kev tshem tawm bisphenol a, thaum Swcnt Mem pom kev ua tau zoo rau ntau yam organic thiab ppcps.
Cov kev tshawb fawb ntxiv tau tshawb txog kev daws teeb meem ib puag ncig (xws li PE Nqi thiab Ionic lub zog) thiab sa) cuam tshuam rau kev ua haujlwm ntawm CNT daim nyias nyias. Cov txiaj ntsig tau qhia tau tias Ph yeej cuam tshuam qhov kev tshem tawm ntawm dyes thiab ppcps. Nyob rau hauv Alkaline cov xwm txheej, daim nyias nyias ua yeeb yam zoo dua thaum tshem tawm cov cationic dyes, thaum acidic tej yam kev mob yog ntau dua rau kev tshem tawm anionic dyes.
Lub CNT cov kua muag qis membrane, txhim kho los ntawm kev sib cav ua haujlwm, txhim kho qhov kev tshem tawm cov tshuaj muaj kuab tshuaj me me molecular. Cov thev naus laus zis no tsuas yog daws cov kev txwv uas muaj kev pheej hmoo tab sis kuj tseem txo cov kuab paug no tab sis kuj tseem muaj kev phom sij hauv ib puag ncig. Nrog kev nce qib tas mus li hauv thev naus laus zis, CNT cov neeg muaj peev xwm tuav tau zoo rau kev kho kom zoo rau yav tom ntej hauv kev kho dej kom zoo, tshwj xeeb hauv kev lag luam pov tseg cov txheej txheem.
