“…The data are in close agreement with those reported in [19] (20 µCi/g dry resin), and [20] (21.3 µCi/g dry resin) for used SuperLig ® 644 resin contacted with Hanford site actual AW-101 waste solutions. …”

SuperLig / Resin / Cesium / Column sorption / Breakthrough curve / ElutionSummary. Column ion exchange tests have been used to demonstrate the ability of SuperLig ® 644 resin to remove 137 Cs from highly alkaline radioactive waste. The column test resulted in 137 Cs removal and overall decontamination factor of 99.6% (lead column) and 517 000 (lag column) respectively. The concentration of 137 Cs in the lag column effluent (0.000423 µCi 137 Cs/mL) was two orders of magnitude below the low-activity waste vitrification limit of 0.087 µCi 137 Cs/mL. The bed volume (BV = 175) at the onset of breakthrough exceeded the requirement of 100 BV at 50% breakthrough. Cesium elution with 0.5 M HNO 3 was adequate with a peak BV of 3.5. C/C 0 = 0.01 occurred at 10 BV of eluant, which is less than the target of 15 BV. Further, 99.99% of sorbed cesium was eluted from the resin. The residual 137 Cs on the regenerated resin after the column operation was 23 µCi/g dry Na + form resin.

“…Many of the same metals detected by ICP-AES were also found in the eluate from the AW-101 testing and include Cr, Cu, Fe, N% Ni, K, Pb, U, and Zn. Many of these same components were also detected during the analysis of the spent resin (Kurath and Wagner 2000) and include C% Co, Cr, Cu, Fe, Na, Ni, Pb, Sr, Zn and Zr. As expected, 137Cswas the dominant radionuclide detected.…”
