Craig-type discontinuous countercurrent solvent extraction apparatus was used for the separation of I/sup 131/ from irradiated telluric acid. Six stages were considered enough for more than 85% recovery of radiochemically pure I/sup 131/. The organic solvent phase (TBP-CCl/sub 4/) could be used repeatedly as a fixed phase without removal from the cell. A millicurie of I/sup 131/ was prepared per cycle in 0.01% KOH aqueous solution, and the specific activity was mC/ approximates 30 mu g of KI. Less than 1 hr was necessary for the complete cycle of separation and no shielding or ventilation was necessary for the operation. (P.C.H.)
