Description
The dissociation and complexation of fulvic acid from weathered coal (from Gong Xian, Henan Province) are studied by means of potentiometric titrations. The effects of salt concentration and functional group heterogeneity on the apparent dissociation constants are characterized. Some characteristics of the binding of the ions Cu(II), Th(IV) and La(III) on this fulvic acid are determined
