EXTRACTION AGENT FOR EXTRACTING ACTINIDES IN OXIDATION STATES +4 AND +6 FROM NITRIC ACID SOLUTIONS Russian patent published in 2010 - IPC B01D11/04

Abstract RU 2400281 C1

FIELD: chemistry.

SUBSTANCE: invention relates to chemical engineering of extracting radionuclides. An extraction agent for extracting actinides in oxidation states +4 and +6 from nitric acid solutions contains tributylphosphate in formals of fluorinated alcohols with volume ratio of formal in the extraction mixture between 50% and 80%.

EFFECT: efficient extraction of actinides in oxidation states +4 and +6 from nitric acid solutions, re-extraction with nitric acid solutions with sufficiently high concentration.
