Abstract
X-ray absorption near-edge structure (XANES) spectra for trace amount of Eu (<1 mg/kg) in natural samples were determined in fluorescence mode using a Bragg-type crystal analyzer system. Effective separation of Eu Lα and Mn Kα emissions by the system allowed us to measure XANES with high sensitivity. Sharpening of the XANES peak by the suppression of the inner-shell lifetime-broadening effect using high energy resolution fluorescence detection (HERFD) also contributed to determination of small amount (= 0.01) of Eu(II) relative to Eu(III) based on XANES spectra.
