Investigation of the transport of actinide-bearing soil colloids in the soil-aquatic environment

PDF Version Also Available for Download.

Description

Research indicated that organic and inorganic particles strongly influence the distribution ratios of Am(III), Np(V), and Cm(III). Gel Permeation chromatography experiments indicate that distribution ratios are stongly dependent on the concentration of particles having molecular weights of approximately 50,000. These molecules or particles are probably polymers of humic acid. Particle-size dependent distribution ratios have been obtained for the Ritzville, Burbank, and Fuquay soils. Equations are derived to demonstrate the relationship between humic acid complexes and distribution ratios.
