Title:
METHOD FOR COEXTRACTING NEPTUNIUM AND PLUTONIUM
Document Type and Number:
Japanese Patent JPH07246301
Kind Code:
A
Abstract:

PURPOSE: To easily coextract neptunium and plutonium without generating secondary waste liquor.

CONSTITUTION: A nitric acid mixed soln. of neptunium/plutonium is subjected to photooxidation by irradiation with UV. Since the valence of the neptunium is adjusted so that all of the neptunium is converted into water-soluble hexavalent neptunium and the valence of the plutonium is adjusted so that the plutonium is converted into tetra- or hexavalent plutonium extractable in an org. phase, these metals are easily coextracted.
