The ability of orange peel and sawdust waste, a waste material derived from the commercial processing of orange and wood production, to remove Pb(II), Ni(II) and Cd(II) ions from aqueous solution was determined. Biosorption by raw waste materials could be a cost effective technique for removing metals ions from aqueous solutions. The performance of a new biosorbents system, consisting of biological matrix which was magnetically modified by iron oxide nanoparticles, was studied. The use of low-cost and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods. The sorption of metal ions was investigated by determination of adsorption isotherms. The binding of metal ions was found to be dependent on pH. Magnetic orange peel and magnetic sawdust were found to be an effective sorbent for metal ions in the range of low concentrations.
