Behavior of selenium and arsenic in HCl and HNO3 on TRU, TEVA, DGA, and Pb extraction chromatography resins
The uptake behavior of 73 As and 75 Se was studied in HCl and HNO 3 -H 2 O 2 solutions on commercial extraction chromatography resins (TEVA, TRU, DGA, and Pb resin). There was no uptake of 73 As or 75 Se from HNO 3 media. From HCl, there was 75 Se uptake at high concentrations on all the resins and...

solutions on commercial extraction chromatography resins (TEVA, TRU, DGA, and Pb resin). There was no uptake of
73
As or

media. From HCl, there was
75
Se uptake at high concentrations on all the resins and no uptake of
73
As. Separations of
75
Se and
73
As on these resins have high yields and high radiopurity for
73
As, but limited recovery of
75
Se. TRU and TEVA resin may have potential for use in isotope generators as
75
Se can be retained for at least 26 days with repeated elutions. |
