Abstract :

This study investigates the adsorption of zinc (II) ions onto red mineral soil. The red mineral soil has been applied as an adsorbent for the treatment of Zinc contaminated synthetic waste water. Adsorption study was assured on the basis of adsorption parameters pH, initial metal ion concentration, dosage amount, contact time and temperature. The batch equilibrium experiment results reveal that, at optimized conditions of high pH (pH 6), high metal ion concentration, more interaction time with larger amount of adsorbent (red mineral soil) shows highest adsorption efficiency. The equilibrium data were best studied on Freundlich, isotherm model. The FTIR, SEM and AAS analysis is done for required adsorption studies.
