Crystalline silicotitanate manufactured and marketed by UOP as IONSIV IE-911 and an ammonium molybdophosphate-polyacrylonitrile (AMP-PAN) composite sorbent have been evaluated for the removal of cesium from Idaho National Engineering and Environmental Laboratory (INEEL) concentrated acidic tank waste. Equilibrium isotherms were generated with simulated concentrated tank waste solutions and fit to the Langmuir equation. Nonequilibrium sorption was evaluated in column tests employing 1.5 cm3… Expand
