METHOD FOR SORPTION EXTRACTION OF PENTAVALENT NEPTUNIUM FROM AQUEOUS SOLUTIONS

摘要

FIELD: inorganic chemistry, chemical technology. SUBSTANCE: invention relates to chemistry of transuranic elements. Method involves application of fibrous complex-forming sorbent of type "POLIORGS" with groups of hydrazidine and amide oxime. Sorbent is used as nonwoven fibers. Sorption of neptunium (V) is carried out from saline aqueous solutions at pH = 4-10. Invention can be used for sorption extraction of pentavalent neptunium from aqueous solutions and used for analytical and technological aims. EFFECT: enhanced degree of neptunium extraction. 3 cl
