The coordination chemistry of Cm^III, Am^III, and Ac^III in nitrate solutions: an actinide L₃-edge EXAFS study.

ABSTRACT: Understanding actinide(iii) (An^III = Cm^III, Am^III, Ac^III) solution-phase speciation is critical for controlling many actinide processing schemes, ranging from medical applications to reprocessing of spent nuclear fuel. Unfortunately, in comparison to most elements in the periodic table, An^III speciation is often poorly defined in complexing aqueous solutions and in organic media. This neglect - in large part - is a direct result of the radioactive properties of these elements, which make them difficult to handle and acquire. Herein, we surmounted some of the handling challenges associated with these exotic 5f-elements and characterized Cm^III, Am^III, and Ac^III using An^III L₃-edge X-
