Abstract:	Solvent extraction of ²⁴¹Am, ²⁴⁴Cm, ²⁴⁹Bk, ²⁵²Cf, ²⁵³Es, ^152–154Eu and ²³³U from 1 to 15 M HNO₃ solutions by a number of polydentate neutral organophosphorus compounds has been studied. The effect of the reagents structure on their extraction capacity, and selectivity has been investigated. Extraction by tetraphenylmethylenephosphine dioxide, which proved to be the best reagent studied, has been studied in detail. It is shown that this compound may be used for quantitative group extraction and concentrating of transplutonium elements from 1 to 15 M HNO₃ and from nitrate solutions of arbitrary concentration and acidity.
