Novel Template Sorbents for Separation of Americium(III) from Nitric Acid Solutions: Search of Optimal Ion-Imitator of AmIII.
Publication date: 2014
Journal: Helvetica Chimica Acta
Abstract: A series of new template sorbents that enable selective and effective sorption of AmIII from 0.5 to 4M HNO3 solutions containing high concentrations of FeIII and ZrIV was synthesized from (ethenyl)(diphenyl)phosphine oxide. LaIII, CeIII, and PrIII were used as template elements imitating the properties of AmIII. The highest efficiency of separation of AmIII from high amounts of FeIII and ZrIV was displayed by the CeIII-based sorbent
Template and target information: americium ion, AM(III), cerium ion, Ce(III)
Author keywords: Template sorbents, Americium(III), lanthanides, Ionic radius, Phosphine oxide, copolymerization
