Özet (Çeviri)
Studies about heavy metal interactions with soils have received increasing attention due to land disposal of different kinds of sewage sludge. Of particular importance in this field is the sorption process of heavy metals which influences their mobility, determining their distribution between the liquid and the solid phase of the soil. In this work, heavy metal (Cu,Cd,Cr) sorption experiments was carried out on six Turkish soil samples. The adsorption capacities (K) and adsorption intensities (l In) of these soils relating to these metals were investigated by batch shaking method. The interactions between the four major adsorption characteristics, namely pH, cation exchange capacity (CEC), clay and organic material contents of the soils, and the retention of Cu, Cd, and Cr was also examined by batch column experiments. The experimental results of were fitted to Freundlich adsorption isotherm model. The adsorption capacities of the experimental soils were higher for cadmium than copper. Chromium in the form of dichromate was not adsorbed by the soils. During the column experiments the retention of the heavy metals tended to increase as concentration increased and retention was very high in the worked range of concentrations. Copper and cadmium showed similar behavior all through the experiments.
