Abstract  

The extraction of Eu with Amberlite LA-2, TBP and HDEHP from HF, HCl, HBr, H2SO4, CH3 COOH and KI solutions was investigated. The extraction of Eu with TBP and LA-2 is small over a wide range of concentrations. The extraction of Eu with HDEHP from HCl, HBr, and H2SO4 is inversely proportional to the third power of the acid concentration, while the extraction from KI is proportional to the square of the extractant concentration. The extraction by the three extractants from H2SO4 in presence of small amounts of hydrogen halides is small. These extraction data can be used to separate Eu from Th and many of the fission products. The presence of water-miscible alcohols and acetone generally increases the extraction of Eu from H2SO4 and KI solutions.
