Sorption--desorption studies on argillite. I. Initial studies of strontium, technetium, cesium, barium, cerium, and europium

Abstract
Distribution ratios were determined for sorption--desorption of radioactive tracers between Eleana argillite available from the Nevada Test Site and a water prepared to be representative of the natural groundwater composition. The measurements were preformed at 22{sup 0}C and 70{sup 0}C under atmospheric oxygen conditions. The order of increasing distribution coefficient by element at both temperatures is Tc(VII), Sr, Cs, Ba, Eu, and Ce. The effects of surface area and mineralogy were also investigated. 34 figures, 26 tables.
