Changes in Structure and Content Humic Substances in Soil During the Laboratory Simulated Fires

Open access


The paper deals with the process of thermal degradation of humic substances in soil samples exposed to increased temperature. To determine the basic properties of humic substances, humic and fulvic acids are used conventional fractionation chemical laboratory methods. To determine changes in the chemical structure, the method of use of FT-IR ATR spectroscopy technique.
