- Abstract
Grafting of quaternary ammonium group is the main goal of this research for uranium recovery. The sorbent was investigated by FTIR, SEM–EDX, elemental analysis, thermogravemetric and XPS analyses, it shows high and fast loading performance (176.49 mg U g−1), the total equilibrium reached within 25 min, fitted by first order rate equation and Sips model for sorption kinetics and isotherms respectively. Complete desorption achieved after 30 min by 1.0 M NaCl in 0.1 M H2SO4. Sorption/desorption was measured after 10 cycles without significant loss in the capacity. Finally, the sorbent applied for uranium recovery of leaching solution from sulfuric acid on gibbsite bearing shale ore materials.
