Abstract: This compilation is the result of removal of lead and cadmium ions from aqueous solutions by using adsorption process. The adsorbent used for this purpose is activated carbon prepared from P. hysterophorus which is a pernicious weed and spread vastly all over. Effect of pH, dose, temperature, contact time and initial concentration of metal ions was assessed and adsorption experiments were conducted in batch wise manner. Optimum pH for lead and cadmium ions were observed to be 5.5 and 6.0 and optimum dose came out to be 0.1 g and 0.2 g respectively. The obtained experimental data were tried to fit various adsorption isotherms Langmuir, Freundlich, Redlich-Peterson, Sips, Temkin and Radke-Prausnitz isotherms using MATLAB. In which, Langmuir, Sips and Radke-Prausnitz showed the best fit for Pb(II) and Sips and Radke- Prausnitz fitted best for Cd(II). From experiments conducted at different time intervals, pseudo first and pseudo second order rate equations were analyzed, among which pseudo second order rate equation model exhibited high correlation coefficient (R2=0.99) for both the metals.
