Malonamides as new extractants for nuclear waste solutions

  • 1. Commissariat a L'Energie Atomique, Fontenay-aux-Roses (France)

Description

A new class of extractants has been investigated: pentaalkylpropane diamides. Due to their chelating effect on metallic cations, they extract trivalent actinides such as Am3+ and Cm3+ from acidic nitrate nuclear waste solutions. These solvents are completely incinerable and do not generate large amounts of waste. A review is provided of their chemical properties, leading to the choice of the proper molecule. The results of a bench-scale experiment performed in a mixer-settler battery are presented
