Humic acid characterization of colombian soil by disc electrophoresis and ir spectroscopy following gel filtration



Humic acid characterization of colombian soil by disc electrophoresis and ir spectroscopy following gel filtration



Journal of Chromatography 209(3): 421-431



Humic acid extracted from Columbian soil was separated into fractions by means of gel filtration on Sephadex G-25 and G-75. A high proportion of acid has a MW > 50,000 daltons. Analysis of these fractions by disc electrophoresis on polyacrylamide gel and by IR spectroscopy shows a highly aromatic character for humic and inorganic materials bound to the small fractions.
