Characterization of Humic Substances Extracted from Different Sediments of the Lower Normandy Region
The characterisation of humic substances is very important and has been carried out by many investigators using a variety of methods. In this paper the humic acids extracted from different sediments of Basse Normandie have been studied. Elementary analysis, TG and DTA methods together with EPR and polarographic methods have been used to characterise humic substances. The results are related to commercially available humic acid (Fluka) or to humic acid extracted from foreign peat.
