摘要：

A purpose-built spectroelectrochemical cell for in situ fluorescence XAFS (X-ray absorption fine structure) measurements of bulk solution species is described. The cell performance was demonstrated by the collection of europium L-3-edge XANES (X-ray absorption near edge structure) during constant-potential electrolysis of 14.2 mM EuCl3.6H(2)O in 1 M H2SO4 aqueous electrolyte, Additionally discussed in this report are the probabilities of 2p(3/2)-->5d electronic transitions pertaining to Eu-III and EUII ions, Implications for the use of XANES in studying intermediate-valence materials, and some potential applications of the presently reported spectroelectrochemical cell are described.
