FIELD: medicine, medicinal technology, pharmacology, analytical chemistry.
SUBSTANCE: method involves analysis of alkaline solutions of humic acids and qualitative assay is carried out in the region from 310-800 nm (absorption bands with maximum at 350 nm and 390 nm). The quantitative content of humic acid is determined at wavelength 350 nm by calibrating plot. Invention provides the lower cost and labor consumptions, higher precision, sensitivity and reproducibility in analysis of humic acids content in peloids. Invention can be used for qualitative and quantitative determination of humic acids in peloids.
EFFECT: improved method of analysis.
