- •
Pd(II) recovery by commercial activated carbons is studied in leaching solutions.
- •
Palladium uptake is higher in HCl than in HNO3 solutions.
- •
The uptake of Pd(II) is insensitive to pH (1–3) and salinity (0.1–0.6) levels.
- •
Pd(II) uptake occurred through a series of adsorption and reduction reactions.
- •
The adsorption step involves the carbon surface rather than oxygenated groups.
