  • Abstract
    The influence of the concentration on the behaviour of a soil fulvic acid is analyzed by conductimetric titrations. The values obtained (variation of molar conductivity between ca. 134 to 82 and variation of the degree of coverage between 0.31 to 0.16 when the concentration of fulvic acid rises from 20 to 100 mg l−1) are explained by the counterion condensation theory and parameters derivated are calculated. The influence of small quantities of an organic solvent is also analyzed.
