Three different Chitosan/ZrO₂ (CTS-ZrO₂) composites are prepared by sol–gel then, used as bio-sorbent for Cs (I) and Co (II) metal ions from aqueous solution in this study. Characterization of (CTS-ZrO₂) composites is done through different analytical techniques. Optimizations of the adsorption affecting factors are explored via batch mode. The adsorption equilibrium attained after 60 min for initial metal ion concentration is 100 mgL⁻¹ and at optimum pH 9 and 6 for Cs (I) and Co (II), respectively. Kinetic modelling is applied and the adsorption reaction followed pseudo 2^nd order. The adsorption capacity for Cs (I) at pH 9 and 25^oC is 124.6 mgg⁻¹ and for Co (II) at pH 6 and 25^oC is 111.1 mgg⁻¹. The thermodynamic parameters showed the adsorption reaction is spontaneous and endothermic.

通过溶胶-凝胶制备三种不同的壳聚糖/ZrO ₂ (CTS-ZrO ₂ ) 复合材料，然后用作本研究中水溶液中 Cs (I) 和 Co (II) 金属离子的生物吸附剂。(CTS-ZrO ₂ ) 复合材料的表征是通过不同的分析技术完成的。通过批处理模式探索吸附影响因素的优化。60 分钟后，初始金属离子浓度达到 100 mgL ^{-1 时}达到的吸附平衡，Cs (I) 和 Co (II) 的最佳 pH 值分别为 9 和 6。动力学模型被施加和吸附反应遵循准2^次的顺序。Cs (I) 在 pH 9 和 25 ^o C的吸附容量为124.6 mgg ^-1对于 Co (II)，在 pH 6 和 25 ^o C 下为 111.1 mgg ^-1。热力学参数表明吸附反应是自发吸热的。
