Özet
In order to evaluate the sorption behavior of Cd2+, Pb2+, and Cu2+ ions on humus rich O and E/EB soil zones of mudstone and spilite, batch equilibrium experiments were performed at 25 degrees C in competitive component adsorption systems. Heavy metal ions like Cd2+, Pb2+, and Cu2+ were selected for adsorption studies considering their contribution as toxic metals in the environment. The adsorption of the heavy metal ions was studied at different initial solute concentrations and pH levels. The initial metal concentrations ranged from 7.0 10(-3) to 1.0 10(2) mg/L. The adsorption isotherms were obtained and firstly, Scatchard plot analysis (q/C vs. q) was used to investigate the adsorption behavior of the metal ions. However, in the adsorption of metal ions, deviation from linearity in the plot of q/C versus q was observed, indicating the presence of multi-model interaction and non-Langmuirean behavior. The adsorption behavior of these metal ions on soil zones of spilite and mudstone was expressed by the Freundlich isotherms. Adsorption constants and correlation coefficients were calculated from Freundlich plots.
