Solid-phase extraction of plutonium in various oxidation states from simulated groundwater using -benzoylphenylhydroxylamine.

Solid-phase extraction of plutonium in different individual and mixed oxidation states from simulated groundwater (pH 8.5) was studied. The extraction of plutonium species was carried out in a dynamic mode using DIAPAK C16 cartridges modified by -benzoylphenylhydroxylamine (BPHA).
