A. Busnot et al., CHARACTERIZATION OF HUMIC SUBSTANCES EXTR ACTED FROM DIFFERENT SEDIMENTS OF THE LOWER NORMANDY REGION, Thermochimica acta, 254, 1995, pp. 319-330
The characterisation of humic substances is very important and has bee
n carried out by many investigators using a variety of methods. In thi
s paper the humic acids extracted from different sediments of Basse No
rmandie have been studied. Elementary analysis, TG and DTA methods tog
ether with EPR and polarographic methods have been used to characteris
e humic substances. The results are related to commercially available
humic acid (Fluka) or to humic acid extracted from foreign peat.
