Extraction of Cd2+ and Am3+ Ions into Organic and Fluorous Solvents with a TPEN Chelating Agent bearing a Fluoroalkyl Substituent
Introduction of polyfluorinated alkyl groups into TPEN (N,N,N',N'-tetrakis(2-pyridylmethyl)ethylenediamine) derivatives provides soft metal ion extracting agents with high acid tolerance. The TPEN derivative bearing a pentafluoropropoxy substituent efficiently extracts Cd2+ and Am3+ into organic and fluorous solvents.
