| dc.description.abstract | In this study, adsorption of undesirable Cu (II) ion with bentonite in industrial wastewater was investigated atdifferent temperature, pH and time intervals. Adsorption experiments were started with an adsorbent amount of0.5 grams. Optimum pH determination experiments were carried out in the first stage of the adsorptionexperiments. The optimum pH determined after the experiments was determined as 5.0. Adsorption rates andadsorbed metal ions concentration increased with increasing concentrations of starting Cu (II) ions up to 25 mg /L and 500 mg / L in a medium containing 0.5 g of adsorbent. In the isotherm studies, isotherms were plotted andisotherm constants were calculated and it was clearly observed that the adsorption system, Langmuir andFreundlich isotherms. When the Gibbs free energy (?G) values calculated at different temperatures are taken intoconsideration, it is observed that the Cu (II) ions have negative values, for 100 mg/L and lower especially at lowconcentrations, and thus the reactions take place spontaneously for these concentrations. The compatibility of theadsorption system with the Langmuir and Freundlich isotherms was investigated, and it was observed that theadenomatoid system adhered to Langmuir and Freundlich. Based on the results, it is concluded that the amount ofmetal retained on the surface increases with temperature increase. Values (n> 1) were obtained for the experimentsperformed at each concentration of Cu (II) ions (up to 500 mg / L at 25 mg / L). | |
