Activated carbon: ke mofuta oa adsorbent e seng polar e sebelisoang ho feta. Ka kakaretso, e hloka ho hlatsuoa ka dilute hydrochloric acid, e lateloa ke ethanol, ebe e hlatsoa ka metsi. Kamora ho omisa ho 80 ℃, e ka sebelisoa bakeng sa kholomo ea chromatography. Granular activated carbon ke khetho e ntle ka ho fetisisa bakeng sa kholomo ea chromatography. Haeba e le phofo e ntle ea khabone e kentsoeng, hoa hlokahala ho eketsa palo e nepahetseng ea diatomite e le thuso ea filthara, e le ho qoba sekhahla sa phallo e liehang haholo.
Activated carbon ke ntho e seng polar adsorbent. Phatlalatso ea eona e khahlanong le gel ea silica le alumina. E na le kamano e matla bakeng sa lintho tse seng polar. E na le matla a matla a adsorption ka har'a tharollo ea metsi 'me e fokola ka har'a motsoako oa organic. Ka hona, matla a elution ea metsi ke a fokolang ka ho fetisisa le solvent ea tlhaho e matla. Ha motsoako oa adsorbed o ntšoa ho tsoa ho khabone e kentsoeng, polarity ea mokelikeli oa fokotseha, 'me matla a adsorption a solute ho khabone e kentsoeng a fokotseha, 'me matla a leseli a matlafatsoa. Likarolo tse qhibilihang ka metsing, tse kang li-amino acid, tsoekere le glycosides, li ne li arotsoe.
