Abstract

Chromium glycerate solutions are exposed to X-ray absorption fine structure analysis to clarify the local structure around the chromium atom by the use of a laboratory XAFS system. The chromium solution is stabilized by addition of water soluble polyvinyl alcohol so that after excess water, the solution is a kind of homogenized “sol” without any apparent charge to the solution state. The new technique has been developed, because chromium is an element which has relatively small X-Ray absorption.

The comformations of two novel chromium glycerate compounds, which are prepared under both NH4OH and NaOH basic conditions, are examined with XANES and EXAFS techniques. From these experiments, it is suggested that these two chromium glycerates may have Cr-O-Cr bridge bonds consisting of chromium dimer complexes in common.
