Origin of heat-induced structural changes in dissolved organic matter

Original language description

Humic substances play an important role in many environmental processes such as sequestration and transport of hydrophobic compounds. The supramolecular character of humic substances imparts high flexibility of the aggregates associated with their variable reactivity under different conditions. In this study, heat-induced transitions and character of the hydration shell of sodium salts of humic and fulvic acids originating from various sources were investigated using ultrasonic velocimetry in the temperature interval from 5 to 90 °C. Results clearly showed differences in stability and characteristics of the hydrated states at concentrations above and below 1 g L-1 with the exception of Pahokee peat fulvic acids. It has been concluded that predominantlythe relaxation part of the adiabatic compressibility plays an important role below 1 g L-1 in contrast to both relaxation and intrinsic parts of the compressibility being important at higher concentrations. Dilution brought several tempe
