Sequential separation of actinide elements from highly radioactive Hanford waste by ion exchange methods
Description
A simple, rapid method has been developed for the sequential separation of actinide elements from samples with high salt content such as these resulting from efforts to characterize Hanford storage tank waste. Actinide elements in 9M HC1 solution are introduced into an anion exchange column. U(VI), Np(IV) and Pu(IV) are retained on the column while Am(III) passes through. Plutonium is eluted first, reductively; after which neptunium and then uranium are eluted with mixtures of HC1 and HF. The Am(III) is purified by cation exchange in a nitric acid system. 14 refs., 2 tabs
