ANION EXCHANGE IN A LARGE-SCALE AGITATED BED
An agitated ion exchange column was adapted for use in a large radiochemical separations plant. Tests with nonradioactive solutions showed that ion exchange resin could be charged to and discharged from the column through typical plant piping and without the use of mechanical valves. With the agitator turning, the bed passed solutions containing 400 ppm of finely divided silica whereas a fixed bed became plugged. The pressure drop through the column and the absorption characteristics of an anionic complex of thorium nitrate were compared under agitated, pulsed, and fixed bed conditions. (auth)
