Modelling sorption of radionuclides on sorbent containing surface sites with variable charges: Ni-Sr-goethite system

PDF Version Also Available for Download.

Description

Results are presented on the retardation of radionuclides by sorption processes during host rock-ground water interactions. Studies are being performed at Yucca Mountain as part of a site selection for the underground disposal of high-level radioactive wastes. Tuff has a high sorption capacity for radionuclides. Several types of zeolites and montmorillonite, as well as goethite are known to occur in the tuff. Ion exchange phase equilibrium theory is used to describe sorption of mixtures of nickel and strontium ions in aqueous phase on goethite at a constant pH.
