Ultrasonic Spectroscopy and Fractal Analysis in the Study on Progressive Aggregation of Humic Substances in Diluted Solutions

Original language description

High resolution ultrasonic spectroscopy was used to study progressive aggregation and structural changes in diluted aquatic solutions of humic substances over the concentration range from 0.001 g/L to 3 g/L. For this purpose, both sodium salts (fulvates)and protonized forms of fulvic acids and sodium salts of humic acids (humates) were used; the origin of humic substances covered wide range of sources. Obtained results confirmed previously published statement about the progressive aggregation of humicsubstances in diluted solutions. The method allowing the treatment of obtained data by fractal analysis was developed and tested. Determined dependency of fractal dimension on concentration revealed clear differences in mechanisms of aggregation of individual humic and fulvic samples. In fact the value of fractal dimension 2.5 was determined for the concentration 3g/L; diluting the solution caused increasing in fractal dimension value up to 3 for concentrations around 0.01 g/L.
