Ion exchange resins used in uranium mines for neutral in-situ leaching mining often experience a reduction in their working exchange capacity owing to contamination. Three regeneration techniques-ultrasonic regeneration, (HCl+H2O2) regeneration, and (HCl+H2O2) treatment-ultrasonication regeneration methods-were employed to treat the resin, and the efficiencies of the methods were compared. The results indicated that the combination of (1 mol HCl+0.5% H2O2) treatment with 10 min ultrasonication exhibited the highest regeneration effectiveness. The industrial applicability verification test show...
