Description

Benzyldibutylamine is a suitable extractant for the separation of Am(III) and trivalent lanthanides from acidic nitrate solutions. The effect of lanthanides and yttrium on the extraction of Am(III) was studied under conditions modelling the contents of these components in spent nuclear fuel. The separation factors αsub(Am/Ln) were evaluated for the optimum conditions found for the separation of Am(III) from the lanthanides. The coextraction of nitric acid and water into the organic phase is discussed. (author)
