Electrochemical and spectroscopic studies of the complexed species of models of nitrohumic acids derived from phthalic acid

Journal of the Brazilian Chemical Society, 1998
The study of model compounds is necessary in order to obtain information about complex organic substances as in the case of humic substances (HS). These substances are potential organic fertilizers and have other important functions in soils, natural ...
