Abstract

Humic acids were extracted from brown coals of the Kara-Keche deposit (Kyrgyzstan) and characterized. The solubility of humic acid in aqueous urea solutions was studied. The solvation excess of urea over water on humic acid in solution was calculated. The possibility of simultaneous binding of urea molecules on three independent centers of humic acids was shown. An estimation of humic acid molecular dimensions in aqueous urea solutions is given.
