The Role of Carboxyl and Hydroxyl Groups of Humic Acid in Removing AuCl<sub>4</sub><sup>-</sup> from Aqueous Solution

The Role of Carboxyl and Hydroxyl Groups of Humic Acid in Removing AuCl<sub>4</sub><sup>-</sup> from Aqueous Solution

Humic acid (HA) extracted from peat soil according to the recommended procedure of the International Humic Substances Society (IHSS) has been tested to remove AuCl4- from aqueous solution. The removal was optimum at pH 2.0 and it was mainly dictated by attachment through hydrogen bonding to unionize...
