1.Nyob ntawm nws tus kheej pore qauv
Activated carbon yog ib hom microcrystalline carbon cov khoom uas yog tsim los ntawm carbonaceous cov ntaub ntawv nrog dub tsos, tsim nyob rau hauv pore qauv, loj tshwj xeeb deg cheeb tsam thiab muaj zog adsorption muaj peev xwm.Activated carbon cov khoom muaj ib tug loj tus naj npawb ntawm pom micro pores, 1 g activated carbon. cov khoom siv micro pores, yuav nthuav dav tom qab thaj chaw saum npoo tuaj yeem ncav cuag 800-1500 square metres, kev siv.Yog, qhov chaw sab hauv ntawm lub qhov hws nyob rau hauv ib qho activated carbon particle qhov loj ntawm cov nplej nplej yuav yog cov Qhov loj ntawm chav nyob.Nws yog cov tsim tsim, xws li tib neeg capillary pore qauv, kom cov pa roj carbon activated muaj kev ua haujlwm zoo adsorption.
Activated Carbon Adsorption yog ua los ntawm kev sib sau ntawm cov pa roj los yog kua rau saum npoo ntawm cov pa roj carbon activated, cov khoom siv tsis zoo. Cov txheej txheem no yog siv los tshem tawm ntau yam, yaj cov kab mob los ntawm dej, huab cua, thiab cov kwj deg.
2. Lub zog ntawm adsorption ntawm molecules
Kuj hu ua "van der Waals gravity".Txawm hais tias qhov ceev ntawm molecular motion yog cuam tshuam los ntawm kub thiab khoom, nws yog ib txwm tsiv nyob rau hauv lub microenvironment.activated carbon vim qhov kev sib nrig sib attraction ntawm molecules, thaum ib tug molecule yog activated carbon puab lub qhov. Nyob rau hauv lub activated carbon inner pore, vim kev sib nrig sib attraction ntawm molecules, yuav ua rau kom ntau molecules attracted, kom txog rau thaum lub filling activated carbon puab pore.
Activated carbon adsorption txoj cai: Tsim nyob rau hauv particle nto txheej sib npaug ntawm qhov chaw concentration, ces cov impurities ntawm cov organic tshuaj adsorbed rau activated carbon hais, pib siab adsorption nyhuv. Tab sis dhau sij hawm, activated carbon adsorption muaj peev xwm yuav tsis muaj zog mus rau txawv degrees, cov nyhuv adsorption kuj txo.Yog hais tias lub thoob dej yug ntses dej turbidity, siab organic cov ntsiab lus nyob rau hauv dej, activated carbon yuav sai sai no yuav tsis pom muaj nuj nqi. Cov pa roj carbon activated yuav tsum tau ntxuav tsis tu ncua lossis hloov.
