Investigation of Adsorption of Landfill-Leachate Transport in Clay Soils
Abstract
Leachates contained in most modern waste- containment facilities are aqueous solutions containing a complex mixture of inorganic and organic species. In the Turkey, solid wastes are primarily disposed in landfills. Landfills may potentially leak leading to contamination of underlying soils and groundwater. Compacted clays or mixtures of local soils with clay are frequently used to achieve very low hydraulic conductivity barriers and prevent subsurface contamination. In this study, experiments have been carried out to determine the adsorption capacity of the clay soils for some metal ions (Mn, Cu, Fe, Pb, Zn) in a batch reactor systems. For this purpose the leachate and clay soils was taken from Şile- Kömürcüoda Landfill Area on the Asian side of Istanbul. A series of experiments were carried out to determine the most efficient adsorbent amount with the leachate. In first step, the optimum amount of clay was determined by using clay in various amounts with constant amount of the leachate. In second step, the same amount of leachate was contacted with the optimum amount of clay in shaker to determine the effect of contact time. In last step, in order to determine the effect of temperature, all experiments were carried out at three different temperatures. In this study, after all experiments, the optimum amount of the clay was found 0.25 g. Depending on this result, optimum temperature was found 35 0C and recovery efficiencies up to 99 percent were achieved for Mn, Cu, Fe, Pb, Zn ions.
