Owing to the less energy consumption, positive impact on the environment, and prospect of providing clean water resources, anion exchange membranes (AEMs) are promising materials for acid recovery from various industrial wastewater/effluent. Based on the diffusion dialysis process, AEMs selectively allow rapid proton permeation while efficiently retaining metal ions. To enhance the efficiency of the acid recovery process, precise control of macromolecular architecture and chemical composition that enables high hydrophilicity, proton conductivity through the membrane, and ion exchange capacity is required. In this direction, we report on the one-step fabrication of novel poly (ionic liquids)-based AEMs by the free radical polymerization of 1-butyl-3-vinyl imidazolium bromide, acrylic acid, styrene, and acrylonitrile under sunlight. The effect of monomer composition in an AEM matrix on the structural, physicochemical, surface, thermal, and proton conductivity is investigated. The experimentally determined acid dialysis coefficient ($U_{H^{+}}$) obtained with synthesized poly (ionic liquid) based membranes PILM-1 and PILM-2 were 7.3 ± 2 and 9.2 ± 2 mh⁻¹ at room temperature (25 °C), while separation factors (SF) were 88.9 ± 3 and 50.1 ± 2, respectively. Both the $U_{H^{+}}$ (>700 times) and SF (>4 times) are significantly values higher compared to the commercial AEM DF-120 (0.009 mh⁻¹ and 18.8 for $U_{H^{+}}$ and SF, respectively). Thus, this study demonstrates the potential of the prepared AEMs as an alternate to deliver cost-effective, scalable, and rapid acid recovery compared to the currently existing technology.

由于能耗低，对环境有积极影响以及提供清洁水资源的前景，因此阴离子交换膜（AEM）是从各种工业废水/废水中回收酸的有前途的材料。基于扩散渗析过程，AEM有选择地允许快速质子渗透，同时有效保留金属离子。为了提高酸回收过程的效率，需要精确控制大分子结构和化学组成，以实现高亲水性，质子通过膜的电导率和离子交换能力。在这个方向上，我们报道了在阳光下，通过1-丁基-3-乙烯基咪唑鎓溴化物，丙烯酸，苯乙烯和丙烯腈的自由基聚合，一步一步制备新型的基于聚（离子液体）的AEM。研究了AEM基质中单体组成对结构，物理化学，表面，热和质子传导率的影响。实验确定的酸透析系数（${ü}_{H^{+}}$用合成的基于离子液体的膜获得的PILM-1和PILM-2在室温（25°C）下分别为7.3±2和9.2±2 mh ^-1，而分离系数（SF）为88.9±3和50.1 ±2，分别。这俩${ü}_{H^{+}}$（> 700倍）和SF（> 4倍）的值明显高于商用AEM DF-120（0.009 mh ^-1和18.8${ü}_{H^{+}}$和SF）。因此，这项研究表明，与现有技术相比，制备的AEM具有替代潜力，可提供具有成本效益，可扩展性和快速的酸回收率。
