EXAFS studies of lanthanide coordination in crystalline phosphates and amorphous phytates

PDF Version Also Available for Download.

Description

As part of the DOE Efficient Separations and Processing Integrated Program, techniques are being developed to stabilize radioactive and hazardous contaminants to prevent their migration from buried wastes. This report is part of a study to immobilize actinide ions in the near-surface environment by reacting them with organophosphorus complexants that decompose to phosphates. Nd and Gd ions were used as models for Pu, Am, and Cm ions; phytic acid was used as the complexant. Solid Nd and Gd phytates were prepared and the coordination characterized by EXAFS.
