- •
A mineral adsorbent was synthetized from modified Algerian clay.
- •
We studied the adsorption of heavy metal ions on the adsorbent.
- •
Fitting of experimental isotherm data by non-linear Langmuir and Freundlich models were studied.
- •
The adsorbent shows high adsorption capacity and good selectivity for Cu and Zn.
