Extraction of americium, curium, and californium with LN resin from HCl and HNO3

The uptake of Am-241, Cm-244 and Cf-249 with LN resin was studied in HCl and HNO3 solutions with concentrations ranging from 0.02 to 2.5 M. There is high uptake at concentrations < 0.1 M in both acids for all three isotopes with decreasing uptake at higher concentrations and negligible extraction at >= 0.6 M. Californium has a higher extraction than americium and curium, which are extremely similar. Kinetics studies showed rapid uptake of all three isotopes. Column studies were performed to demonstrate the separation of Am-241 and Cf-249, and a bulk separation including nine stable lanthanides along with Am-241, Cf-249, and Y-88.
