ABSTRACT

The  sorption  of  Pu  from  nitric  acid  solutions  containing  oxalate/fluoride  was  studied  using  an indigenously  available  macroporous  bifunctional phosphinic acid (MPBPA) resin. Batch experiments were carried out to obtain the distribution data of Pu(IV) with a view to optimize conditions forits recovery from nitric acid waste solutions containing oxalate or fluoride ions. The measurements showed high distribution ratio (D) values evenin the presence of strong complexing ions, like oxalate and fluoride, indicating the possibility of recovery of Pu from these types of waste solution.Column studies were carried out using this resin to recover Pu from the oxalate supernatant waste solution, which showed that up to 99% of Pucould be adsorbed on the resin. Elution of Pu loaded on the resin was studied using different eluting agents.
