M.  aCharacterization of humic like substances obtained by chemical oxidation of eucalyptus charcoal.h[electronic resource]  c2005  aThe objective of this experiment was to characterize the chemical and physical properties of humic-like substances synthesized from Eucalyptus spp. charcoal produced at various carbonization temperatures, for comparison to naturally humified pyrogens in soils. The chemical properties of the synthetic products are characterized by elemental, thermogravimetric, FTIR and 13C NMR analyses.  ahumic substances  aChemical oxidation  aEucalyptus charcoal1 aBENITES, V. de M.1 aMADARI, B.
