Abstract

This research wasaccomplished to appraise the performance of Cyperus Rotundus Stalk (CRS) in adsorption of lead heavy metalofaquatic environments. For this purpose, the batch system was used for review the effect pH, Mixing time, adsorbent particle size and temperature for Pb(II) removal on the CRS. The highest lead removal efficacy was achieved in pH=6 and it was considered as the optimum pH. The result indicated the maximum Pb(II) adsorption at the contact time of 90 min which implies that increase in contact time lead to a higher lead uptake.The amount of R2using the pseudo-second-order are greater than compare with others models.Influence of temperature was determined byusing thermodynamic parameters and the results showedremoval of lead on the CRS was endothermic, spontaneousandfeasible.
