The separation of Americium from light lanthanides by Cyanex 301 extraction
Description
The extraction behavior of tracer amount of 241Am3+ and 152-154Eu3+ from sodium nitrate solution by 1 M Cyanex 301 in kerosene are quite similar. But in the presence of macro amount of Nd + Pr nitrates (0.2-0.7 M), Cyanex 301 saponified to 16% selectively extracts 241Am3+. The separation factors Am/Eu and Am/Nd + Pr are of 500 and 600 respectively. In a batch counter current fractional extraction process with 3 extraction stages and 3 scrubbing stages, the organic phase contained 99.9% 241Am and <1% Nd + Pr. The radiolytic stability of the extractant has been observed. (orig.)
