Abstract For nuclear hydrometallurgical separation process development, it is necessary to demonstrate the stability of the extracting systems, since it is well known that radio-and hydrolytic degradation leads to undesirable effects, such as a decrease in selectivity, poorer phase separation and third-phase formation. Recently, we have developed a new family of bis-diglycolamide (bis-DGA) molecules with high distribution coefficients (D) for Eu III over ...
