Izici nokusetshenziswa kwekhabhoni eyenziwe yasebenza

I-carbon eyenziwe yasebenza: uhlobo lwe-adsorbent engeyona eye-polar esetshenziswe kakhulu. Ngokuvamile, idinga ukugezwa nge-dilute hydrochloric acid, ilandelwe yi-ethanol, bese igezwa ngamanzi. Ngemuva kokumiswa ku-80 ℃, ingasetshenziselwa ikholomu chromatography. I-granular activated carbon iyona khetho engcono kakhulu yekholomu ye-chromatography. Uma kuyimpuphu ecolekileyo yekhabhoni eyenziwe yasebenza, kuyadingeka ukwengeza inani elifanele le-diatomite njengesihlungi sosizo, ukuze uvikele isilinganiso sokugeleza okuhamba kancane kakhulu.
I-carbon eyenziwe nge-adsorbent engeyona eye-polar. Ukukhangisa kwayo kuphambene ne-silica gel ne-alumina. Inobudlelwano obuqinile bezinto ezingekho polar. Inamandla amakhulu we-adsorption kusixazululo samanzi futhi ibuthakathaka ku-solvent organic. Ngakho-ke, amandla we-elution wamanzi abuthakathaka futhi i-solvent organic inamandla. Lapho i-adsorbed element ihlukanisiwe ne-carbon eyenziwe yasebenza, ubukhulu be-solvent buyancipha, namandla we-adsorption we-solute ku-carbon esebenzayo ayancipha, namandla we-eluent we-eluent ayathuthukiswa. Izinto ezinamanzi ancibilikayo, njengama-amino acid, ushukela nama-glycosides, bezihlukanisiwe.
