- •
Removal of Cu and Pb from aqueous solutions by biosorption onto pine cone shell was studied.
- •
The competence between metal cations takes place in this binary system.
- •
Pine cone shell had more affinity for lead than for copper ions.
- •
Extended Sips model was the best to reproduce experimental results in batch systems.
- •
Desorption studies indicated that Cu,Pb-loaded PCS could be eluted by 0.3 M HCl.
