Abstract: Natural bentonite is one of the most commonly used adsorbent in the removal of heavy metals because of its low cost, easily availability and high mechanical and chemical stability. In the present study, natural bentonite was firstly characterized by using Brunauer-Emmett-Teller (BET), X-ray diffractometry (XRD), Fourier transform infrared (FTIR) spectroscopy and thermogravimetric (TG) analysis methods. Secondly, natural bentonite was used as an adsorbent for the determination of the adsorption ability of lead(II) ions from aqueous solution at various pHs, temperatures and concentrations. The obtained results indicate that natural bentonite is an effective adsorbent for the removal of heavy metals from aqueous solutions.
