Final Purification of the Heavy Actinides From the First Four Campaigns of the Tru Program.

Separation of Milligram Quantities of 252Cf from Multigram Quantities of 244Cm and 243Am

“…After CHOPPIN et al [3] reported that ammonium Λ-hydroxyisobutyrate (AHIB) is a superior elutriant for separating the actinide elements, AHIB has been extensively used on a small scale to separate the transplutonium elements [4]. High pressure cation exchange systems have been applied to various lanthanide-actinide separations with either elution development [5,6] or displacement development [7, 8. ] BAYBAHZ and OBB [6] separated the transcurium elements on a milligram scale by pressurized cation exchange with AHIB as an elutriant.…”

HÖHLEIN and coworkers [9,10] have optimized the conditions for the separation of multimilligram amounts of 242 Cm and 241 Am on a low-pressure column by an automatic PH-gradient elution technique with AHIB as an elutriant.…”

Multigram Group Separation of Actinide and Lanthanide Elements by LiCl-Based Anion Exchange

“…Temporary glass equipment was installed and the LiCl AIX process was successfully scaled to a useful level (5). Tramex product solutions, containing from 4 to 10 g of 244 Cm (11 to 23 V!…”
