The natural ecosystem will continually deteriorate for decades by the leakage of Cs and Sr isotopes. The exploration of the new materials or techniques for the efficient treatment of radioactive wastewater is critically important. In this study, a dielectric barrier discharge (DBD) configuration was constructed to operate the non-thermal plasma (NTP). The NTP was incorporated into the synthesis of polyaluminum chloride (PAC) in two different procedures to intensify the synthesis of PAC (NTP-PAC) and enhance the further removal of Cs and Sr from wastewater. The employment of NTP in two procedures both had significantly changed the physicochemical characteristics of PAC materials, which facilitated the further adsorption application of NTP-PAC on the treatment of Cs⁺ and Sr²⁺. Different molecular, morphological, and adsorption characteristics were confirmed to the NTP-PAC materials. The heterogeneous adsorption of the NTP-PAC can be appropriately fitted by both the pseudo-first-order kinetic model and the Elovich model. Both physisorption and chemisorption reaction mechanisms were ensured for the heterogeneous adsorption of the NTP-PAC material towards Cs⁺ and Sr²⁺, which guaranteed the excellent adsorption performance of NTP-PAC materials compared to PAC. The electron collisions caused by NTP with alum pulp created highly reactive growth precursors and intensified the nucleation and hydrolysis polymerization of PAC. The employment of NTP explicitly broadens the reaction pathways between PAC and cationic contaminants in the aqueous environment, which expands the application area of PAC materials in environmental sustainability.

由于 Cs 和 Sr 同位素的泄漏，自然生态系统将持续恶化数十年。探索有效处理放射性废水的新材料或新技术至关重要。在这项研究中，构建了介质阻挡放电 (DBD) 配置来操作非热等离子体 (NTP)。NTP 以两种不同的方法被加入到聚合氯化铝 (PAC) 的合成中，以加强 PAC (NTP-PAC) 的合成，并促进进一步去除废水中的 Cs 和 Sr。NTP在两个过程中的使用均显着改变了PAC材料的理化特性，有利于NTP-PAC在Cs ⁺和Sr ^{2+处理中的进一步吸附应用}. NTP-PAC材料证实了不同的分子、形态和吸附特性。NTP-PAC的非均相吸附可以通过伪一级动力学模型和Elovich模型适当拟合。^{保证了 NTP-PAC 材料对 Cs +}和 Sr ²⁺的非均相吸附的物理吸附和化学吸附反应机制，这保证了NTP-PAC材料与PAC相比具有优异的吸附性能。NTP与明矾浆引起的电子碰撞产生了高反应性的生长前体，并加剧了PAC的成核和水解聚合。NTP的使用明确拓宽了PAC与水环境中阳离子污染物之间的反应途径，扩大了PAC材料在环境可持续性中的应用领域。
