Abstract

Fulvic acids (FA) and humic acids (HA) were extracted from two horizons of a minerotro-phic peat bog in Galicia (NW Spain). The samples were characterized and their acid base properties studiedwith the techniques commonly used for this type of determinations: UV-Vis, FT-IR, 13C NMR spectrosco-pies, elemental analysis and potentiometric titrations
