Determination of trace silver in plutonium by pulse anodic stripping voltammetry
- 1. China Institute of Atomic Energy, Beijing (China)
Description
A method for precise determination of trace silver in plutonium by pulse anodic stripping voltammetry was developed. The experimental conditions were optimized. In solution of 0.1 mol/L HNO3-0.1 mol/L KNO3, silver was accumulated on the Nafion-modified glassy carbon electrode surface at -0.5 V (vs SCE) for 300 seconds and then a sensitive oxidation peak of Ag was observed by anodic stripping voltammetry. The peak current is proportional to the concentration of Ag+ in the range of 10- 100 μg/L. The detection limit of Ag+ is 5 ng/mL and the recovery for addition standard is 90%-109%. This is simple, sensitive and selective method. (authors)
