Removal Of Metal Ions

The capacity of synthesized zeolites from Brazilian coal ash for the removal of metal ions from aqueous solutions has been investigated. Equilibrium data obtained have been found to fit both the Langmuir and Freundlich adsorption isotherms. The zeolitic material prepared with coal ash from baghouse filter showed the highest removal efficiencies. The metal ion selectivity of this product was determined as: Pb2+ > Cd2+ > Cu2+ > Zn2+ > Ni2+. The maximum cation exchange capacities were between 32.9 and 246.9 mg g-1. Tests showed that the zeolitic material was suitable for removal of zinc from electroplating effluent.
