Sorption--Desorption Studies on Argillite. I. Initial Studies of Strontium,Technetium,Cesium,Barium,Cerium,and Europium.

摘要

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 22exp 0 C and 70exp 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. 34figures, 26tables.
