Lub hauv paus ntsiab lus ntawm activated carbon adsorption

1.Nyob ntawm nws tus kheej pore qauv

Cov pa roj carbon activated yog ib hom microcrystalline carbon cov khoom uas feem ntau yog ua los ntawm cov khoom siv carbonaceous nrog cov xim dub, tsim cov qauv pore sab hauv, thaj chaw loj tshwj xeeb thiab muaj zog adsorption muaj peev xwm.Activated carbon cov khoom muaj ntau qhov pom tsis pom micro pores, 1 g activated carbon cov ntaub ntawv micro pores, yuav nthuav dav tom qab qhov chaw saum npoo tuaj yeem ncav cuag 800-1500 square metres ntawm thaj chaw pores. Ib qho activated carbon particle qhov loj ntawm cov nplej nplej tuaj yeem yog qhov loj ntawm chav nyob.Nws yog cov no tau tsim, xws li tib neeg capillary pore qauv, kom cov pa roj carbon activated muaj kev ua haujlwm zoo.

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 lub ntiajteb txawj nqus".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 puab lub qhov capture mus rau hauv lub activated carbon puab pore, vim muaj kev sib nrig sib attraction ntawm molecules, thaum ib tug molecule yog activated carbon puab lub qhov nqus mus rau hauv lub activated carbon puab pore, vim muaj kev sib nrig sib attraction ntawm molecules. sau activated carbon inner 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.
