N2 - Extraction of nitric acid, perchloric acid, americium, and europium with dialkyldiarylamides of 2,6-pyridinecarboxylic (dipicolinic) acid in polar fluorinated solvents (diluents) was analysed. Among the extractants studied N, N′-diethyl-N, N′-ditolylamide dipicolinate is characterized by the best extraction properties. On passing from nitric to perchloric acid solutions extraction of metals sharply increases. Extraction of americium from nitric acid solutions is significantly greater as compared with europium (separation coefficient reaches 6), whereas extraction of americium and europium from perchloric acid solutions is nearly similar. The effect of diluent on the extraction was analyzed; for different diluents the maximum of extraction from perchloric acid solutions shifts form 3 to 6 M.
