Abstract
Abstract
This paper describes the development of a radioanalytical procedure to separate Am3+ and Cm3+ that relies on chromatography with the TRU® resin available from Eichrom Technologies, Inc. Although the TRU chromatographic materials are not currently recommended for the separation of the trivalent actinides from each other, our work demonstrates their suitability. We explored parameters such as nitric acid concentration, column length, and flow rate; standard chromatographic parameters such as resolution, theoretical plates, and total separation time are reported for each variable. The advantages of the method described herein include use of a commercially available product and no application of an organic solvent during elution. Optimal resolution between the Am3+ and Cm3+ was achieved with the slowest flow rate.
