Abstract
In the present study various separation methods were investigated for the recovery of actinides from aqueous waste solutions. Extraction behavior and recovery of U(VI) from acidic waste solutions has been examined with Tri-iso-Amyl Phosphate (TiAP) impregnated on XAD-7. Recovery of Am from acidic waste solutions using octyl (phenyl)-N,N-diisobutylcarbamoylmethylphosphine oxide (CMPO) impregnated XAD-7 resin has been examined. Recovery of plutonium from acidic waste solution was carried out using a synergistic mixture of Di-2-ethylhexyl phosphoric acid (D2EHPA) and Tri-n-octyl phosphine oxide (TOPO).
