Thermodynamic Studies to Support Actinide/Lanthanide Separations
- Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States)
Thermodynamic data on the complexation of Np(V) with HEDTA in a wide pH region were re-modeled by including a dimeric complex species, (NpO2)2(OH)2L26- where L3- stands for the fully deprotonated HEDTA ligand and better fits were achieved for the spectrophotometric data. The presence of the dimeric complex species in high pH region was verified for the first time by the EXAFS experiments at Stanford Synchrotron Radiation Laboratory (SSRL).
