摘要：
The extraction of strontium from nitric acid medium was investigated employing DCH18C6 in aliphatic alcohols as the diluents. 80% Butanol-20%, octanol mixture was found to give higher D-Sr values as compared to other alcohols investigated. A linear correlation between the organic phase water content and D-Sr was observed, based on which the extraction mechanism was postulated. Effect of anion, cation, extractant concentration, nitric acid concentration and temperature on D-Sr was also studied. Conditions for recovery (> 90%) were arrived at and selectivity with respect to other interfering fission products was observed with most of the metal ions studied. (C) 1997 Elsevier Science B.V.
