Cov pa roj carbon activated, raws li ib puag ncig tus phooj ywg adsorbent, muaj zog adsorption thiab catalytic kev ua tau zoo, cov ntaub ntawv raw txaus thiab kev nyab xeeb siab, acid thiab alkali tsis kam, kub tsis kam, insoluble hauv dej thiab organic solvents, yooj yim rov tsim dua thiab lwm yam zoo, muaj zog adsorption muaj peev xwm rau cov organic. Cov kuab paug yaj hauv dej xws li benzene tebchaw, phenolic tebchaw, roj av thiab cov khoom siv roj av, thiab lwm yam. Nws kuj muaj cov txiaj ntsig zoo tshem tawm cov kuab paug organic uas nyuaj rau tshem tawm los ntawm kev lom neeg thiab lwm yam tshuaj, xws li chroma, methylene xiav surfactants, herbicides, insecticides, hluavtaws dyes thiab ntau yam hluavtaws organic tebchaw. Tsis tas li ntawd, cov pa roj carbon activated kuj muaj peev xwm adsorption muaj zog rau cov hlau hnyav hauv electroplating khib nyiab thiab smelting dej khib nyiab. Nws muaj qhov pom tseeb pom tseeb ntawm cov dej turbidity, thiab tuaj yeem tshem tawm cov ntxhiab tsw txawv txav thiab tsw ntxhiab tsw hauv dej. Nws kuj muaj kev lim dej zoo rau cov kab mob. Yog li ntawd, cov pa roj carbon activated tau txais kev saib xyuas ntau dua hauv kev kho dej. Txawm li cas los xij, vim yog cov yam ntxwv ntawm cov pa roj carbon zoo tib yam, xws li cov hmoov tshauv siab, qhov ntim me me, qhov dav ntawm micropores, thaj chaw tshwj xeeb me me thiab tsis zoo adsorption selectivity, thiab qee qhov kev txwv ntawm nws cov pab pawg ua haujlwm saum npoo thiab cov khoom siv hluav taws xob, nws cov adsorption thiab Kev tshem tawm cov pa phem yog txwv, deb ntawm kev ua kom tau raws li cov kev cai ntawm kev lag luam hauv tsev thiab txawv teb chaws. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau hloov kho nws cov qauv thiab cov khoom kom ua rau nws muaj peev xwm adsorption thiab txo qhov siab ntawm dej paug.
Activated carbon lim yog cov txheej txheem ntawm kev cuam tshuam cov pa phem nyob rau hauv lub xeev ntawm kev ncua nyob rau hauv dej, thiab cov teeb meem raug tshem tawm yog thaiv nyob rau hauv qhov sib txawv ntawm activated carbon. Qhov pore loj thiab porosity ntawm lub lim txheej nce nrog qhov nce ntawm qhov loj me ntawm cov pa roj carbon activated. Ntawd yog, lub coarser qhov me me ntawm cov pa roj carbon activated, qhov loj dua qhov chaw kom haum rau cov teeb meem tshem tawm. Nws qhia tau hais tias lub peev xwm pom tau zoo dua, cov pa phem nqa lub peev xwm nce, thiab cov pa phem cuam tshuam qhov ntim tau nce. Nyob rau tib lub sijhawm, qhov loj dua qhov pore loj ntawm activated carbon lim txheej, ntau qhov teeb meem raug tshem tawm hauv dej tuaj yeem thauj mus rau txheej tom ntej ntawm cov txheej txheem lim dej. Nyob rau hauv qhov xwm txheej ntawm kev tiv thaiv tuab txaus, cov teeb meem raug tshem tawm tuaj yeem cuam tshuam ntau dua, yog li cov txheej txheem nruab nrab thiab qis qis tuaj yeem ua lub luag haujlwm cuam tshuam zoo dua, thiab cov dej phwj cuam tshuam ntawm chav tsev nce.
Hais lus nruj me ntsis, lub peev xwm ntawm cov pa roj carbon activated kom khaws cov teeb meem raug tshem tawm los ntawm thaj chaw uas tau muab los ntawm cov pa roj carbon activated. Thaum tus nqi qis qis, lub peev xwm pom ntawm chav tsev feem ntau yog los ntawm kev tshuaj xyuas ntawm cov pa roj carbon activated, thiab thaum tus nqi ntws nrawm, lub peev xwm pom tau los ntawm adsorption ntawm activated carbon hais rau saum npoo. Nyob rau hauv cov txheej txheem pom, qhov loj dua qhov chaw ntawm thaj chaw uas tau muab los ntawm cov pa roj carbon activated, qhov muaj zog adhesion rau cov khib nyiab hauv dej.
