Sorption of Actinides from Aqueous Solutions Under Environmental Conditions

  • G. W. Beall

Abstract

The sorption of americium, neptunium, and plutonium has been studied on a suite of thirty pure minerals and one granite as a function of solution pH, salinity, and redox potential. Three major factors controlling sorption have been identified. These three major factors are pH (for hydrolyzable ions), chemi-sorption reactions at the surface of minerals that contain strong complexing ions, and redox reactions with ferrous iron contained in various minerals. It appears that simple cation exchange does not play a significant role in the pH range of most interest in groundwaters. The implications of these findings for nuclear waste disposal are discussed.
