摘要：

The extraction efficiency of some perfluorinated phenols for the removal of Cs+ and Sr2+ from aqueous solutions is reported. The perfluorinated phenols C6F5OH and 2,3,5,6-C6F4HOH have been shown to extract Sr-90(2+) or Cs+ from aqueous solutions into a 100: 1 mixture of toluene and pyridine in reasonable efficiencies, using radio-tracer and ICP-OES techniques. Additionally uranium, Fe-59(3+) {as a model for Pu(IV)} and Eu3+ {as a model for Am(III)} were investigated, with only iron not being successfully extracted.
