Lub pores ntawm xyoob charcoal yog dominated los ntawm cov loj qhov, thaum activated carbon yog loj, lub cev activated carbon yog dominated los ntawm micropores, thiab tshuaj activated carbon yog dominated, thiab cov active carbon tsim los ntawm txawv activation txheej txheem tsis zoo ib yam. Xyoob charcoal yog tsuas yog adsorbing ib co macromolecular tshuaj, nrog rau ntau yam kab mob. Cov pa roj carbon activated muaj cov qauv pore sib txawv thiab siv rau ntau qhov chaw nyob ntawm seb hom adsorption. Txawm li cas los xij, qhov adsorption ntawm cov pa roj carbon activated muaj zog dua li cov xyoob charcoal ntawm cov khoom (xws li cov pa phem xws li formaldehyde, benzene, ammonia, thiab lwm yam) muaj ib txoj kab uas hla me me. Ntxiv mus, cov active carbon adsorption yog heev tsom, thiab sib txawv apertures yog siv los adsorb ntau yam.
