Chitosan/zeolite-A hybrid structure (CS/Z.A) was synthesized and characterized as a multifunctional and environmental adsorbent for the Cd (II) and As (V) ions. The adsorption capacities of CS/ZA for Cd (II) and AS (V) are 170 mg/g and 125 mg/g, respectively which are higher values than several adsorbents in literature. The kinetic study demonstrates Pseudo-First-order behavior for the Cd (II) adsorption process and Pseudo-second order for the As (V) uptake reactions. The Cd (II) and As (V) uptake reactions follow the Freundlich equilibrium behavior with heterogeneous and multilayer adsorption properties. The kinetic and equilibrium studies in addition to the Gaussian energy {6.35 kJ/mol [Cd (II)] and 9.44 kJ/mol [As (V)]} demonstrate physical properties for the Cd (II) adsorption mechanism and more chemical behavior for the As (V) adsorption mechanism. The thermodynamic study declares exothermic, spontaneous, and favorable adsorption reactions for Cd (II) and As (V) by CS/Z.A composite. The CS/Z.A is of significant capacity for Cd (II) and As (V) ions in the existence of other competitive dissolved anions (PO₄³⁻, NO₃⁻, and SO₄²⁻) and other metals [Zn (II), Co (II), and Pb (II)]. Finally, the CS/Z.A composite is a recyclable product and can be applied in effective Cd (II) and As (V) decontamination processes for five runs.

壳聚糖/沸石-A 杂化结构 (CS/ZA) 被合成并表征为 Cd (II) 和 As (V) 离子的多功能和环境吸附剂。CS/ZA 对 Cd (II) 和 AS (V) 的吸附容量分别为 170 mg/g 和 125 mg/g，高于文献中的几种吸附剂的值。动力学研究证明了 Cd (II) 吸附过程的伪一级行为和 As (V) 吸收反应的伪二级行为。Cd (II) 和 As (V) 吸收反应遵循 Freundlich 平衡行为，具有多相和多层吸附特性。除了高斯能量 {6.35 kJ/mol [Cd (II)] 和 9 之外的动力学和平衡研究。44 kJ/mol [As (V)]} 展示了 Cd (II) 吸附机制的物理性质和 As (V) 吸附机制的更多化学行为。热力学研究表明 CS/ZA 复合材料对 Cd (II) 和 As (V) 进行放热、自发和有利的吸附反应。在存在其他竞争性溶解阴离子 (PO) 的情况下，CS/ZA 对 Cd (II) 和 As (V) 离子具有显着的容量₄ ^3-、NO ₃ ^-和SO ₄ ^2- )和其他金属[Zn (II)、Co (II)和Pb (II)]。最后，CS/ZA 复合材料是一种可回收的产品，可用于有效的 Cd (II) 和 As (V) 净化工艺五次。
