Delineated were differential 4th degree absorption spectrum UV-VIS range for standardized humid acids produced by "Fluka". These acids were separated through selective extraction (acid, alcoholic, alkaline). Determined was wavelength for which distinct, well separated, symmetrical peaks characteristic for particular compounds were found. The similar procedure were applied to separate the same sort of acids extracted from 4 Polish peat deposits. Certified are the presence of hymatomelanoic acid, fulvic acid, humic acid in examined peat of low type. These acids occurred in different quantity and proportions.
