Studies were made of the dipicrylamine-- nitrobenzene system for possible use in cesium extraction from fission product wastes. Synthetic and actual Purex wastes were tested. The extraction of cesium by dipicrylamine appears to obey the ion-pair mechanism and is proportional to the dipicrylamine concentration, the reciprocal of the aqueous sodium content, and a decrease in temperature. The extracted cesium is readily stripped with dilute acid, and the extraction and stripping are rapid. Dipicrylamine is sufficiently radioresistant; it requires 2 x 10/sup 8/ r for its total destruction. The solubilities of nitrobenzene and dipicrylamine in alkaline wastes were found low enough for minimal losses in extraction processes. (D.L.C.)
