Abstract

In this study, the ability to adsorb U(VI) metal ions from aqueous solutions on the natural Kula volcanic adsorbent, which is both economically and naturally supplied, was characterized. The effects of pH, amount of adsorbent material, concentration of uranium ions, temperature, and contact time, which are among the parameters affecting the adsorption of U(VI) ions on the natural Kula volcanite, were investigated. According to the experimental results of the adsorption of U(VI) ions on natural Kula volcanite, Langmuir, Freundlich, and D-R isotherm models were evaluated, and according to the obtained data, the adsorption of U(VI) ions showed the best compatibility with Langmuir and D-R isotherms. In the study, a series of experiments were carried out at five different (298.15, 303.15, 308.15, 313.15, 318.15 K) temperatures, and thermodynamic parameters, such as ΔG°, ΔH°, and ΔS° for the uranium ion were calculated, and it was determined that the adsorption was spontaneous and endothermic. According to the results obtained from this study, it can be said that the adsorption ability of natural Kula volcanite in removing U(VI) ions from aqueous solutions is quite high.
