1:1 ZnO/Chitosan nanocomposite (nZnOCS nanocomposite) successfully prepared by sol–gel method and used as a sorbent for Cs(I) and Sr(II). The prepared samples characterized by different analytical techniques as FTIR, SEM, TEM, XRD, particle size analyzer, TGA/DTA, and pore size distribution. Optimization of pH of the medium, contact time, initial metal ion concentration and temperature for the sorption reaction performed. The sorption reaction kinetics follows pseudo-2nd order. The monolayer capacities at 298 K are 253.81 and 116.1 mgg⁻¹ for Cs(I) and Sr(II), respectively. The sorption process is spontaneous and endothermic.

通过溶胶-凝胶法成功制备了 1:1 ZnO/壳聚糖纳米复合材料（nZnOCS 纳米复合材料），并用作 Cs(I) 和 Sr(II) 的吸附剂。通过FTIR、SEM、TEM、XRD、粒度分析仪、TGA/DTA和孔径分布等不同分析技术对制备的样品进行表征。为进行的吸附反应优化介质的 pH 值、接触时间、初始金属离子浓度和温度。吸附反应动力学遵循伪二阶。Cs(I) 和 Sr(II)在 298 K 下的单层容量分别为 253.81 和 116.1 mgg ^-1。吸附过程是自发的和吸热的。
