In this experiment’s kaolin clay was applied as adsorbent material for remove lead (Pb +2 ) from simulated wastewater. Many experiments were done at variance conditions, such as pH, initial concentration of Pb ions and adsorbent weight. Highest removal efficiency (85.1) % was obtained at 2g adsorbent weight,10 mg/L initial metal concentration with pH5. Consequences appeared that kaolin clay is perfect in removing Pb +2 from wastewater. Adsorption isotherm of Pb +2 ions by kaolin clay was conducted with Freundlich and Langmuir isotherms which had good effects, that reported. FTIR images of kaolin clay before and after adsorption were completely verified the uptake of Pb +2 The aim of current work is to use kaolinite clay for investigating adsorption properties of Pb +2 from polluted water.
