Abstract
Methods and agents for extracting cesium and strontium ions from aqueous solutions, including aqueous fission product waste solutions, are disclosed using substituted metal dicarbollide and/or dicarbaextranide ions containing one or more chemical groups that increase solubility of the substituted metal dicarbollide or dicarbaextranide ions in non-nitrated, non-chlorinated solvents, or using metal dicarbollide or dicarbaextranide ion-substituted silicones.
