Removal of Am From HNO_3 Solution With Carbon Nanotubes

The removal and recovery of Am in HNO_3 solution with carbon nanotubes(CNTs) are stu-(died).At high HNO_3 concentration,CNTs adsorb little Am,but the adsorption ratio of Am increases greatly with pH value of HNO_3 solution.When pH>5,more than 99.95% of Am can be adsorbed by CNTs.With 1.5 mol/L HNO_3,more than 99% Am can be recovered from CNTs.
