摘要：

The separation of milligram amounts of Cm-248 from Cf-252 is presented. Essentially isotopically pure Cm-248 was obtained from an "old" Cf-252 neutron source by acid leaching. Curium was separated from californium in a cation exchange column combining two different eluents: alpha -HMBA at pH 4.0 for Cf, and alpha -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 Cm-248) free from Cf (Cf-250 < 1.3 x 10(-2) ng and Cf-252 < 4.2 x 10(-3) ng).
