Kinetic Studies of Heavy Metal Removal from Industrial Wastewater by Using Natural Zeolite
The present work involves the study of the removal of Cu2+, Fe3+, Pb2+and Zn2+from synthetic metal solutions using natural zeolite. Laboratory experiments were used to investigate the efficiency of adsorbents in the uptake of heavy metals from industrial wastewater. The kinetic study was used to ide...

The kinetic study was used to identify the effect of parameters that affect the rate of adsorption and evaluated their impact on the efficiency of the zeolite in the removal of heavy metals from industrial wastewater.
