Lub hauv paus ntsiab lus ntawm activated carbon adsorption

1.Nyob ntawm nws tus kheej pore qauv

Cov pa roj carbon activated yog ib yam ntawm cov khoom siv microcrystalline carbon uas yog tsim los ntawm cov khoom siv carbonaceous nrog cov tsos dub, tsim sab hauv pore qauv, loj tshwj xeeb thaj chaw thiab muaj zog adsorption muaj peev xwm.Activated carbon cov ntaub ntawv 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 qhov ua tau 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 kev sib nrig sib attraction ntawm molecules, thaum ib tug molecule yog activated carbon inner qhov capture. 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 ntsiab 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 qhov sib txawv degrees, cov nyhuv adsorption kuj txo.Yog hais tias lub thoob dej yug ntses dej turbidity, siab organic 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.
