Extraction chromatographic studies on Am(III) and U(VI) using Cyanex-923 impregnated Chromosorb W in nitric acid medium
- 1. Radiochemistry Div., Bhabha Atomic Research Centre, Mumbai (India)
Description
The uptake of Am(III) and U(VI) has been investigated under varying nitric acid concentrations (0.01-3 M HNO3) by an extraction chromatographic resin material viz. Cyanex-923 coated on Chromosorb W. Whereas quantitative sorption of U(VI) was observed throughout the [HNO3] range, DAm values showed a maximum at 0.1 M HNO3. Presence of 5 M NaNO3 enhanced the DAm values significantly up to 0.1 M HNO3. In column experiments, breakthrough capacity was evaluated as 42 ± 2 mg of Nd(Am) per gram of the resin material. 1.5 ml of 8 M HNO3 was sufficient to elute ∼ 98.5% of the sorbed Nd(Am). (author)
