X-Ray Absorption Fine Structure Utilizing a Fluorescence Spectrometer: Site Selective Structure Determination of Environmental Catalysts and Adsorbents

摘要

New spectroscopic tool to investigate the site structure of trace amounts of element in complex samples is introduced. The tool also selectively monitors the chemical state of an element by utilizing the chemical shift of each state. The experimental configuration of X-ray absorption fine structure combined with fluorescence spectrometry and the applications to trace amounts of lead and vanadium in heavy-element matrix and to chemical-state-selective measurements for copper catalyst are reviewed.
