The effects of contact time, pH, initial metal concentration and amount of adsorbent on the adsorption process at room temperature 25 ± 2°C were studied. Batch adsorption studies showed that an equilibrium time of 90 min. was required for the adsorption of Cr (III), Cu(II), Zn(II), Cd (II) and Pb(II) on both investigated adsorbents. The maximum metal removal was found to be pH dependent . With an increase in the concentrations of these metals, their adsorption decreased on both of the adsorbents. The experimental data were best fitted to the Temkin isotherm model. Rice husk and Nile rose plant were found to be good metal adsorbents. A case study was also performed to examine the feasibility of using the investigated adsorbents for treating real electroplating wastewater.
