1. Nyob ntawm nws tus kheej cov qauv pore
Cov pa roj carbon ua kom sov yog ib hom khoom siv microcrystalline carbon uas feem ntau yog ua los ntawm cov khoom siv carbonaceous nrog cov tsos dub, tsim cov qauv pore sab hauv, thaj chaw loj thiab muaj peev xwm nqus tau zoo. Cov khoom siv carbon ua kom sov muaj ntau qhov tsis pom me me, 1 g cov khoom siv carbon ua kom sov me me, yuav nthuav dav tom qab thaj chaw tuaj yeem txog 800-1500 square meters, siv. Ntawd yog, thaj chaw sab hauv ntawm cov qhov hws hauv cov khoom siv carbon ua kom sov qhov loj ntawm cov noob mov yuav yog qhov loj ntawm chav nyob. Nws yog cov no tsim tau zoo heev, xws li cov qauv pore capillary tib neeg, yog li cov pa roj carbon ua kom sov muaj kev ua tau zoo adsorption.
Kev nqus cov pa roj carbon activated yog qhov ua rau muaj cov pa roj lossis cov kua sib sau ua ke rau ntawm qhov chaw ntawm cov pa roj carbon activated, uas yog cov khoom khov kho uas tsis muaj zog. Cov txheej txheem no yog siv los tshem tawm ntau yam kuab paug uas yaj hauv dej, huab cua, thiab cov kwj deg.
2. Lub zog ntawm kev nqus ntawm cov molecules
Kuj hu ua "van der Waals gravity". Txawm hais tias qhov ceev ntawm kev txav mus los ntawm molecular yog cuam tshuam los ntawm qhov kub thiab cov khoom siv, nws ib txwm txav mus rau hauv qhov chaw ib puag ncig.activated carbon vim yog qhov sib txuas ntawm cov molecules, thaum ib lub molecule tau activated carbon sab hauv qhov ntes rau hauv lub qhov hluav taws xob sab hauv ntawm cov pa roj carbon, vim yog qhov sib txuas ntawm cov molecules, yuav ua rau ntau lub molecules raug nyiam, kom txog thaum sau cov pa roj carbon sab hauv ntawm cov pa roj carbon.
Txoj Cai ntawm Kev Siv Cov Pa roj Carbon Activated: Thaum cov pa roj carbon activated nyob rau hauv cov khoom me me, cov khoom tsis huv ntawm cov organic yuav raug nqus mus rau hauv cov pa roj carbon activated, thiab qhov no yuav ua rau cov pa roj carbon activated muaj zog heev. Tab sis thaum lub sijhawm dhau mus, cov pa roj carbon activated yuav tsis muaj zog ntau, thiab cov pa roj carbon activated yuav txo qis. Yog tias cov dej hauv lub thoob dej muaj cov organic ntau, cov pa roj carbon activated yuav tsis ua haujlwm zoo. Yuav tsum ntxuav lossis hloov cov pa roj carbon activated tas li.
