Immobilization of radionuclides in the Hanford vadose zone by incorporation in solid phase
EMSL Project ID
2078
Abstract
The objective of the project are: 1. to investigate the effect of aging on the stability of sorption complexes on Al oxyhydroxides surfaces formed from neutralization and homogeneous nucleation of alkaline aluminate solutions; 2. to investigate the sorption/coprecipitation of different contaminants in solids formed from reaction of alkaline aluminate solutions with the Hanford sediments. The XRD analyses that will be conducted at EMSL will help us to determine the components of the newly formed solid phase during dissolution/precipitation processes.
