Cov pa roj carbon activated yog cov khoom siv zoo heev rau kev tshem tawm cov tshuaj lom neeg los ntawm dej thiab cua. Ib qho ntawm nws lub zog tseem ceeb yog nws lub peev xwm adsorptive siab, uas yog qhov tshwm sim ntawm nws thaj chaw loj thiab tshuaj lom neeg rau cov organic molecules. Vim tias cov pa roj carbon activated muaj qhov tsis muaj polar, nws nyiam lwm yam tsis muaj polar molecules zoo li cov hlau nplaum. Qhov no txhais tau hais tias nws muaj peev xwm adsorb ntau dua ntawm adsorbates ntawm tus nqi nrawm dua li lwm cov ntaub ntawv. Tsis tas li ntawd, cov pa roj carbon activated muaj ntau yam thiab tuaj yeem kho tau rau cov hom kab mob tshwj xeeb, ua rau nws muaj txiaj ntsig zoo rau ntau yam kev siv hauv dej thiab huab cua huv.
Cov pa roj carbon activated yog lub npe hu rau nws lub peev xwm adsorptive siab. Hauv adsorption, ib qho adsorbate yog tuav rau saum npoo ntawm cov khoom. Cov pa roj carbon activated tuaj yeem ua tau zoo adsorb ntau yam ntawm cov molecules thiab ions vim nws cov qauv ntxeem tau tshwj xeeb thiab thaj chaw loj. Nws tuaj yeem tshem tawm cov impurities ntawm dej thiab cua, thiab feem ntau yog siv rau hauv huab cua thiab dej purification systems. Cov txheej txheem adsorption tuaj yeem tshwm sim ntawm lub cev lossis cov txheej txheem tshuaj. Lub cev adsorption tshwm sim thaum muaj zog txaus nyiam ntawm cov adsorbate thiab cov khoom nto tuav cov adsorbate nyob rau hauv qhov chaw. Cov tshuaj adsorption tshwm sim thaum cov tshuaj tiv thaiv ntawm cov adsorbate thiab nto tsim cov tshuaj sib txuas, ua rau muaj zog adsorption.
