1.Activated carbon adsorption txoj kev los kho cov dej phwj muaj roj
Oily industrial khib nyiab dej, xws li cov pa phem ntawm dej hiav txwv los ntawm cov roj tanker xau,oil muaj kuab paug thiab pov tseg los ntawm cov chaw tsim khoom, yuav tsum tau ua tiav ntawm ntau theem kom ua tau raws li cov qauv. Vim cov roj yog cov khoom siv organic, nkaus xwbtuskhoomnrog zoo compatibility tuaj yeem nqus thiab tshem tawm,thaumactivated carbon yognrog zoohydrophilicity,uassib xws rau nws cov hydrophilicity yog qhov tsis zoo,nwstshwm simsnyob rau hauv activated carbon adsorption ntawm cov roj muaj ib tug tej yam sab sauv txwv. Qhov no yuav tsum muaj cov organic teeb meem adsorption thiab kev kho ntau theem ntawm cov roj cov kabmob muaj cov dej khib nyiab, thiab tom qab ntawd kev kho zaum kawg nrog cov pa roj carbon activated, txhawm rau txhawm rau nqus cov roj hauv cov dej khib nyiab tag..
2.Cov dej khib nyiab uas muaj cov hlau hnyav hnyav tau kho los ntawm cov pa roj carbon activated adsorption
Cov dej khib nyiab feem ntau yog cov kua khib nyiab ntawm cov tshuaj tiv thaiv, uas muaj ntau cov hlau hnyav xws li mercury thiab chromium uas tsis tau ua tiav. Yog tias cov hlau no tau tso rau hauv cov dej ntws tsis muaj kev kho mob, lawv yuav ua rau muaj kev phom sij rau cov nroj tsuag loj hlob, cov protein metabolism thiab ua pa ntawm cov tsiaj. Cov pa roj carbon activated muaj qhov muaj zog adsorption ntawm qis concentration mercury uas yog cov tshuaj lom tshaj plaws hauv cov dej khib nyiab thiabnwstuaj yeem tshem tawm cov mercury ions zoo.Txawm li cas los xij, at high concentrations, mercury yuav tsum xub muab tshuaj precipitated, thiab ces activated carbon yuav siv tau tag nrho adsorb cov mercury ions seem. Txawm hais tias cov txheej txheem ntawm kev kho cov pa roj carbon monoxide ntawm cov dej khib nyiab uas muaj chromium yog qhov nyuaj heev, nrog rau lub cev adsorption ntawm chromium, txo cov tshuaj lom neeg thiab lub cev tshuaj adsorption, tab sis cov nyhuv yog qhov zoo heev, cov chromium uas muaj cov dej khib nyiab tsuas yog cov pa roj carbon adsorption tuaj yeem tshem tawm cov chromium ion..
3.Kev kho cov dej khib nyiab uas muaj cov xim los ntawm activated carbon adsorption
Kev txhim kho ntawm kev lag luam textile, tshwj xeeb tshaj yog kev lag luam tsoos tsho thiab ntawv kev lag luam hauv xyoo tas los no, nrog rau kev kho tsis tiav ntawm cov dej khib nyiab uas tsim los ntawm cov txheej txheem tsim khoom, uas tau ua rau muaj kev nce nqi ntawm cov dej khib nyiab los ntawm kev lag luam pigment. Raws li cov khoom ntawm hom kev lag luam dej khib nyiab no yog qhov nyuaj heev, qhov concentration yog loj, thiab cov xim zoo sib sib zog nqus, nws nyuaj rau kho nrog cov pa roj carbon activated ib leeg. Feem ntau, rau cov xim muaj dej khib nyiab, feem ntau siv txoj kev kho mob yog oxidize thiab adsorb cov dej khib nyiab ua ntej, tom qab ntawd nqa tawm cov txheej txheem sib cais thiab ntau theem degradation, thiab thaum kawg siv cov pa roj carbon activated los ua qhov sib sib zog nqus decolorization. Qhov zoo ntawm cov pa roj carbon activated rau muaj zog adsorption ntawm cov xim, uas ua rau nws muaj kev cia siab rau hauv kev kho cov xim pigment.
