Kev Adsorption Kub ntawm Cov Pa roj carbon Activated hauv CIL / CIP

  Ntaus Txiaj Ntsig carbon yog ib yam khoom siv organic uas muaj qhov ntxeem tau zoo heev uas muaj cov phaj graphitic, uas sib txuas ua ke los ntawm cov pa roj carbon-carbon bonds. Qhov no tsim cov qauv uas muaj qhov ntxeem tau zoo heev thiab muab thaj chaw sab hauv dav dav, qhov twg "adsorption"tshwm sim. Kev nqus yog ib qho kev ua haujlwm ntawm qhov chaw uas ua rau cov tshuaj sib xyaw "lo" rau ntawm qhov chaw ntawm cov pa roj carbon. 

  Qhov tshwm sim yog qhov tshwm sim ntawm kev nyiam sib txuas ntawm cov molecule los yog cov zog uas muaj nyob rau ntawm qhov chaw carbon. Hauv kub rov qab daim ntawv thov, cov rog adsorption tshem tawm kub ntawm cov tshuaj thiab lo cov hlau sib xyaw rau ntawm qhov chaw carbon.

  Vim tias qhov kev ua tshuaj tshwm sim ntawm qhov chaw ntawm cov pa roj carbon, cov txheej txheem adsorption yooj yim rau kev thim rov qab, ib qho txheej txheem hu ua "desorptionTxawm hais tias nws yog ib qho tseem ceeb kom ua kom kub nqus tau ntau tshaj plaws los ntawm cov kua, nws tseem ceeb ib yam li ntawd kom tshem tawm kub ntawm cov pa roj carbon. Cov molecule uas tseem nyob hauv cov kua tom qab elution lossis stripping txhais tau tias kub uas tsis tuaj yeem rov qab tau. Yog li ntawd, nws yog ib qho tseem ceeb kom xaiv cov pa roj carbon uas nqus tau zoo thiab tshem tawm kom ua tau ntau tshaj plaws thiab ua tau nyiaj ntau tshaj plaws.

  Cov pa roj carbon activated tuaj yeem tsim los ntawm ntau yam khoom siv ua ntej sib txawv, suav nrog thee, txiv maj phaub, ntoo, thiab lignite, uas yog cov khoom siv tseem ceeb siv los ua cov pa roj carbon activated rau kev lag luam. Cov khoom siv pib qhia txog qhov loj me ntawm cov khoom siv carbon activated kawg. Feem ntau, txiv maj phaub yog cov khoom siv ua ntej rau cov ntawv thov rov qab kub vim nws... cov qauv ntawm qhov nruj, cov qhov hws ua haujlwm siab, thiab qhov nyuaj. 

YUAV UA LI CAS COV CARBON ACTIVATED UA HAUJ LWM

  Hauv kev nqus lub cev, cov pa phem raug nqus thiab tuav rau ntawm qhov chaw sab hauv ntawm cov pa roj carbon activated vim yog Van der Waals Forces of attraction ntawm cov pa roj carbon atom thiab lub molecule. Lub zog ntawm kev nyiam txo qis thaum qhov deb ntawm phab ntsa pore thiab lub molecule adsorbate nce ntxiv.
