The Effect of Temperature of SuperLig (R) 644 Cesium Removal from Simulated Hanford Tank Waste Supernate

PDF Version Also Available for Download.

Description

Batch kinetic and column experiments have been carried out at 25, 35, and 45 Degrees C to examine the effect of temperature on SuperLig(R) 644 cesium (Cs) removal from simulated Hanford tank waste supernate. The simulated solution mimicked the composition of the low-activity waste supernate from tank 241-AN-105 in the U.S. DOE Hanford site. Small quantities of toxic metals, such as Cd, Cr, Fe, and Pb were spiked into the simulant to evaluate the metal's competitiveness with Cs for sorption on SuperLig(R) 644 resin. The results indicated that the temperature affects the removal of Cs and metal ions, although the ... continued below

Description

Batch kinetic and column experiments have been carried out at 25, 35, and 45 Degrees C to examine the effect of temperature on SuperLig(R) 644 cesium (Cs) removal from simulated Hanford tank waste supernate. The simulated solution mimicked the composition of the low-activity waste supernate from tank 241-AN-105 in the U.S. DOE Hanford site. Small quantities of toxic metals, such as Cd, Cr, Fe, and Pb were spiked into the simulant to evaluate the metal's competitiveness with Cs for sorption on SuperLig(R) 644 resin. The results indicated that the temperature affects the removal of Cs and metal ions, although the effect was not the same for all metal ions. The extent of Cs removal decreased with an increase in temperature. The Cs capacity at breakthrough point was 0.015, 0.013, and 0.011-mmole/g dry resin at 25, 35 and 45 Degrees C, respectively. The column was effectively eluted to less than 1 Percent (0.1 C/Co) of the feed concentration with approximately 10 BVs of 0.5 M nitric acid. The resin showed limited affinity for toxic metal ions (Cr, Cd, Fe, and Pb) as compared to Cs. Based on the batch kinetic data, the Cs uptake of the resin was not hampered by the presence of the toxic metals in solution.
