Abstract

In recent years, biochar based adsorbents have been given more attention for organic and inorganic pollutants removal. Therefore, in this study, a new low-cost biochar adsorbent derived from Salvadora persica branches (BSP) was prepared, characterized and investigated for removal of U(VI) and Th(IV) radioactive elements from water. The effects of batch adsorption conditions were studied. The maximum removal efficiencies are around 99% for each of U(VI) and Th(IV), with adsorption capacities 85.71 mg g⁻¹ and 84.97 mg g⁻¹ respectively. It has been found the adsorption process of U(VI) and Th(IV) is spontaneous, exothermic and follows pseudo-second-order kinetics.
