Abstract
The polyacrylic weak-acid cation-exchangers Purolite C105 (H+) and Purolite C106 (H+) have been used in batchwise adsorption of UO2+ 2 from nitrate solutions containing 0.01 M of UO2+ 2 at pH 3.2. The two resins, which have a saturation capacity up to about 1.24 mmol UO2+ 2 g−1 resin, showed rapid exchange kinetics. In addition, the resin Purolite C105 (H+) displayed high UO2+ 2 loading in small-scale column operations and retained its capacity after five cycles. Adsorbed UO2+ 2 was rapidly and quantitatively eluted from this resin with 0.1 N H2SO4.Keywords
