摘要：

With the elemental, CHNS - and X-ray fluorescence analysis the chemical composition of humic acids isolated from sapropel was investigated. The acid-base properties of humic acids were determined by potentiometric titration. The number of carboxyl and hydroxyl groups in humic acid, the values of the constants of dissociation of the functional groups determining the sorption properties of the extracted humic acids was established.
