This paper studies the variation of the extraction capacity within a broad series of didentate organophosphorus compounds, from diphosphine dioxides to carbamoylphosphine oxides and phosphonates. The authors consider the disputed questions of the coordination of the actinides when carbamoyl compounds are used and they consider whether an effect of anomalous aryl strenghening exists in these systems. The compounds used are presented. The extraction of microquantities of americium and other actinides was performed from nitric acid media.
