Laboratory studies of radionuclide distributions between selected groundwaters and geologic media. Progress report, January 1-March 31, 1981
- comp.
This quarterly report presents Los Alamos National Laboratory contributions to the Waste/Rock Interactions Technology program, Tasks 3 and 4, for the second quarter of FY-1981. Much of the activity during the second quarter of FY-1981 involved studies of sorption isotherms and of migration in crushed, fractured, and porous materials. Desorption results from batch measurements of plutonium sorption ratio on granite are listed. The rate of uptake of /sup 85/Sr, /sup 137/Cs, /sup 133/Ba, and /sup 152/Eu on climax rock and stripa granite wafers is being studied. Crushed argillite column studies with /sup 85/Sr and /sup 137/Cs are being conducted to study batch sorption desorption ratios. Solid core column studies with tuff are also being performed. Representative sorption ratios that have been obtained by the batch, circulating-system, crushed-rock-column, and, in one case, whole-core-column methodologies for strontium, cesium, and barium are compared. The procedure for the determination of Fe(II) using 4,7-diphenyl-1, 10-phenanthroline has been tested using a Hewlett-Packard model 8450A UV/VIS spectrophotometer. Work has continued on the development of Eh buffers or moderators for use with plutonium and other actinides.
