Actinide speciation using X-ray absorption fine structure spectroscopy

Actinide speciation by means of X-ray absorption fine structure (XAFS) is reviewed with emphasis on actinide speciation in the field of nuclear disposal safety research. The XAFS method, both experimental and theoretical aspects, is concisely presented. Numerous examples of recent research results of actinide speciation using XAFS are discussed. In addition to illustrating important aspects of research dealing with nuclear waste disposal safety, the examples also contain basic and advanced aspects of the XAFS technique, as well as strategies for data evaluation. © 2005 Elsevier B.V.
