Toxic heavy metal used and release in environment through water causing serious pollution. Lead ion metal because of its poisonous quality referred to worldwide as it causes some health issues. Expulsion of lead from wastewater is extremely expected to take care of ecological issues through system Adsorption. Batch study was used to know the optimum parameters. Characterization of adsorbent was done by SEM (scanning electron microscope) that reported surface showed lots of cavities available to accommodate adsorbate molecules. Kinetic modeling was expanded by models (Elovich, Bangham and Pseudo Second order) to get the efficiency of adsorbent at 35°C and 45°C. Equilibrium study checked to get the mechanism of adsorption process at room temperature. Temkin adsorption isotherm well fitted as respective to correlation coefficient (R2). All study was performed by using constant magnetic stirrer at a run of 120 min. Lead ion removal percentage maximum upto 77% found in case of pH.
