The research aims to utilize eggplant (Solanum melongena) leaves to remove and recover U(IV) ions from aqueous solutions. The biomass was characterized by SEM, FTIR and EDS analyses. Eggplant leaves appeared a maximum U(VI) uptake up to 99.87% with sorption capacity:110.97 mg/g at pH 5, 0.09 g dose, 28 °C and 50 min in the batch sorption system. The nonlinear assessment of isotherm and kinetics showed that the sorption system was fitted well by the Freundlich model and the pseudo first-order kinetic model. Also, the thermodynamic study displayed an exothermic of the uptake process. Likewise, the sorption-desorption cycle showed the good stability of eggplant leaves structure up to 9 cycles. The high adsorption capacity, low cost, good stability and biodegradable properties of eggplant leaves make it a good adsorbent for removing and recovering U(VI) ions from aqueous solutions.

该研究旨在利用茄子（Solanum melongena) 离开以从水溶液中去除和回收 U(IV) 离子。通过SEM、FTIR和EDS分析表征生物质。茄子叶出现最大 U(VI) 吸收率高达 99.87%，吸附容量为：110.97 mg/g，pH 5，0.09 g 剂量，28 °C 和 50 分钟在批量吸附系统中。等温线和动力学的非线性评估表明吸附系统符合Freundlich模型和伪一级动力学模型。此外，热力学研究显示了吸收过程的放热。同样，吸附-解吸循环显示茄子叶结构的良好稳定性，长达 9 个循环。茄子叶的高吸附容量、低成本、良好的稳定性和可生物降解的特性使其成为从水溶液中去除和回收 U(VI) 离子的良好吸附剂。
