Acid-basic and complexation properties of a sedimentary humic acid. A study on the Barra Bonita reservoir of Tietê river, São Paulo State, Brazil
Acid-base and complexation properties of humic acid (HA) isolated from a river sediment were studied by potentiometric titration, adopting the discrete site distribution model and the modified Gran functions for data fitting. Six classes of titratable groups were characterized, with pKa values betwe...
