Description
The separation of milligram amounts of 248Cm from 252Cf is presented. Essentially isotopically pure 248Cm was obtained from an ''old'' 252Cf neutron source by acid leaching. Curium was separated from californium in a cation exchange column combining two different eluents: α-HMBA at pH 4.0 for Cf, and α-HIBA at pH 4.8 for Cm. The method was first tested using Sm and Gd as actinide analogues. Excellent separation was obtained, yielding 12.6 mg Cm (11.9 mg 248Cm) free from Cf (250Cf < 1.3 x 10-2 ng and 252Cf < 4.2 x 10-3 ng). (orig.)
