Sequential separation of ulta-trace multi-elements including Pu

Miyamoto, Yutaka   ; Yasuda, Kenichiro   ; Magara, Masaaki  

We developed sequentical and automatic separation of ultra-trace elements in ng-level with a single anion-exchange column. We examined additional separation of ultra-trace Pu with this separation system. Pu was sustained on a column by using a eluent which mostly consisted of acetic acid and other acids, and then the Pu was eluted into a elution fraction for U.
