The work described in this report was undertaken to broaden Hanford's knowledge of radiocesium recovery to include solvent extraction and complement the extensive work which has been in progress for a number of years on carrier precipitation and ion-exchange techniques. Possible advantages of solvent extraction, if an efficient, economical extractant can be found, would include (1) easier integration with solvent extraction processes now being contemplated for other fission products such as strontium, cerium, and rare earths, (2) higher recoveries, or greater degree of cesium removal, than is readily achieved by precipitation technology, and (3) a choice of either continuous or batch operation. Specifically, this paper describes the extraction of cesium by dipicrylamine using nitrobenzene for the organic diluent. Synthetic Purex waste streams as well as actual Purex wastes were tested. 27 refs., 11 figs., 10 tabs.
