The selective extraction behaviour and the stability constants of a series of calixarenes bearing phosphine oxides on their lower rims (see figure) have been studied with alkali and alkaline earth cations, as well as Eu III and Th IV as models of tri‐ and tetravalent actinides. The calixaryl phosphine oxides are much more efficient in extraction than the classical extractants used in nuclear waste treatment.
