Comparison of organic and inorganic ion exchangers for removal of cesium and strontium from simulated and actual Hanford 241-AW-101 DSSF tank waste

“…The inorganic sodium titanate (NaTi) is a powder, produced by Allied Signal (Des Plaines, IL) in collaboration with Professor A. Clearfield at Texas A&M, primarily for strontium removal. CS-100 and resorcinol-formaldehyde (R-F) are two organic ion exchange resins that are commercially available and under consideration for cesium removal from Hanford tank wastes (Brown et al 1995a;Brown et al 1995b;Brown et al 199%;Eager et al 1994;Penwell et al 1994). (a) cs-100 .…”

Evaluation and comparison of SuperLig{reg_sign} 644, resorcinol-formaldehyde and CS-100 ion exchange materials for the removal of cesium from simulated alkaline supernate

“…CS-100 and resorcinol-formalydehyde (R-F) are two organic ion exchange resins that are currently available and under consideration for cesium removal from Hanford tank wastes. CS-100 is a granular (20 to 50 mesh) phenol-formaldehyde condensate polymer ion exchange resin which is commercially available from Rohm & Haas and is considered to be the baseline material for Cs removal at H a r d (Eager et al 1994). (a) R-F is produced by Boulder Scientific and has been shown to exhibit a much greater selectivity and loading for Cs over sodium or potassium than the CS-100 resin (Kurath et al 1994).…”
