RECOVERY AND PURIFICATION Of ~(252)Cf BY HDEHP-LEVEXTREL CHROMATATOGRAPHY

  • The distribution coefficients of Cf (Ⅲ), Cm (Ⅲ) and Eu(Ⅲ) in differentkinds of nitric acid and TTHA solutions are determined. A HDEHP-Levextrelchromatography method is proposed for the recovery and purification of Cf fromCm, Fe, Tb etc. Cf(Ⅲ) is separated from Tb (Ⅲ) with the TTHA eluate(pH3.8). The pH value of the eluate containing Cf and Cm is adjusted to 1.5.Then Cf as well as Cm is absorbed quantitatively from this solution. Finally, Cmand Cf are eluted with 0.50 and 2.0 mol/l HNO_3 respectively. Fe can be deco-ntaminated well by this method. The microgram amount of 252 Cf is recoveredand purified. The recovery of Cf reaches 95%.
