Abstract

Abstract: Since nuclear wastes are the most important wastes in terms of health and the environment, they are evaluated differently within nuclear reactors as well as in terms of their use in medical and industrial applications. In some cases, emergency intervention is necessary due to the amount of radioactivity or the physical and/or chemical conditions. . The purpose of this study is to investigate the adsorption properties of nano Ca3 Y2 B4 O12 (CYBO) material synthesized by the sol-gel combustion method for the adsorption of Thorium (IV) from an aqueous medium. We tested how pH (3–8), the concentration of Th (IV) (25–125 mg/L), amount of adsorbent value (0.005–0.08 g) and temperature (20–60 °C), affect adsorption efficiency. The best possible combinations of these parameters were examined by Response Surface Methodology (RSM) and Artificial Neural Network (ANN). R 2 values for RSM and ANN were 0.9964 and 0.9666, respectively. According to the models, the adsorption capacity under the optimum conditions determined for the RSM and ANN model was found to be 134.62 mg/g and 125.12 mg/g, respectively. Hightlights: Central composite design was separately employed for Th(IV) adsorption onto nano CYBO. The model F values (1.85E-14) indicate is statistically significant. The experimental data were analyzed using isotherm and thermodynamic models. In optimum conditions on RSM, it was obtained 134.62 mg/g of maximum adsorption capacity for Th(IV) ions. A novel borate-based nano material CYBO can be used effectively for Th(IV) removal.
