Steel slag which is a byproduct of the steelmaking process was found to be a low cost and promising adsorbent for the removal of Copper from acidic wastewater. Batch experiments were conducted to study the main parameters such as dosage of adsorbent, particle size initial adsorbate concentration, contact time, kinetic, and pH solution on the sorption of Copper (II) by steel slag.
