Characterization of Pu colloidal and aqueous species in Yucca Mountain groundwater surrogate

PDF Version Also Available for Download.

Description

The speciation and formation of Pu intrinsic colloids from an initial solution of Pu(V) were studied at pH 1, pH 3, pH 6, pIH 8, and pH 11. The medium was a surrogate Yucca Mountain groundwater from well J-l 3 under air atmosphere. The solutions were monitored for several months. Samples were analyzed using liquid scintillation counting, ultra filtration, solvent extraction: photon correlation spectroscopy, and laser-induced photo-acoustic breakdown and emission spectroscopy. Redox potentials were measured periodically. The time dependencies of soluble and colloidal Pu concentrations are reported. The size and concentration of Pu colloid particles were estimated.
