In this research, the resulsts of bentonite characterization by XRF before and after adsorption are presented. The influence of temperature and pH on the capacity and efficiency of adsoption of lead (II) ions using bentonite is determined by adsorption experiments for initial lead (II) concentrations of 200, 300 and 400 mg/L, adsorbent dosage of 1 gram, stirring rate of 200 rpm, contact time between adsorbent and lead (II) ions of 2,5 minutes, for temperature of 25, 30 and 40 °C, and pH of 5 and 8.5. The obtained results showed that at pH 5 adsorption capacity and efficiency decrease with increasing temperature, while for pH 8.5 adsorption capacity and efficiency increase with increasing temperature.
