Abstract
Potentiometric titrations of a soil extracted fulvic acid solutions were ca
rried out varying the initial concentration and the background electrolyte
(KNO3) concentration in the range from 5 10(-3) M to 1.0 M. The mastercurve
approach was tried, but the data did not merge into a single curve, so the
CA and LOGA-1 methods were applied to the experimental Q(pH) curves to ana
lyse the ionic strength effect over the fulvic acid ionization.
