I-activated carbon: iwuhlobo lwe-adsorbent engeyona indawo ezungezile esetshenziswa kakhulu. Ngokuvamile, idinga ukugezwa nge-dilute hydrochloric acid, ilandelwe yi-ethanol, bese igezwa ngamanzi. Ngemuva kokoma ku-80 ℃, ingasetshenziselwa ikholamu yechromatography. I-Granular activated carbon iyinketho engcono kakhulu yekholomu chromatography. Uma kuyimpushana ecolekile yekhabhoni ecushiwe, kuyadingeka ukwengeza inani elifanele le-diatomite njengesihlungi, ukuze ugweme ukugeleza okunensa kakhulu.
I-activated carbon iyi-adsorbent engeyona i-polar. I-adsorption yayo iphambene nejeli ye-silica ne-alumina. Inobudlelwane obuqinile bezinto ezingezona e-polar. Inamandla okukhangisa aqine kakhulu kusisombululo esinamanzi futhi ibuthakathaka ku-organic solvent. Ngakho-ke, amandla e-elution amanzi abuthakathaka futhi isincibilikisi semvelo sinamandla. Uma into ekhangisiwe ikhishwa kukhabhoni eyenziwe yasebenza, i-polarity yesinyibiliki iyehla, futhi amandla okukhangisa e-solute kukhabhoni ecushiwe ayehla, futhi amandla okukhipha i-eluent ayathuthukiswa. Izingxenye ezincibilikayo emanzini, njengama-amino acid, ushukela nama-glycosides, zahlukaniswa.
