The present study deals with the application of treated rice straw, as low-cost agricultural residues, for the adsorptive removal of Cu (II) and Pb (II) from its aqueous solutions. Effects of adsorbent dosage, initial metal ions concentration, and pH as well as contact time on the adsorption of Cu (II) and Pb (II) were investigated. Data obtained from column experiment showed that values of breakthrough capacity was calculated and found to be 6 and 32 mg g-1 for Cu+2and Pb+2, respectively. Scanning Electron Microscope (SEM) of RS powder samples were recorded to explore the morphology of the studied adsorbent. It was clearly seen that the external surface of rice straw is full of cavities. Practical separation experiments for the above-mentioned cations on rice straw column from aqueous waste solutions were carried out. Adsorption increases with increasing the pH of the solution for the studied metal ions and also increases with increasing the amount of adsorbent and stay nearly constant for Cu2+ and Pb2+ metal ions with no significant increase in percentage removal above 0.05 g / 5ml.
