Iodine (I) in the form of iodide ions (I) is an essential chemical element in the human body. Iodine is a nonmetal that belongs to the VIIA group (halogens) in the periodic table. Over the last couple of centuries, the exponential growth of human society triggered by industrialization coincided with the use of iodine in a wide variety of applications, including chemical and biological processes. However, through these processes, the excess amount of iodine eventually ends up contaminating soil, underground water, and freshwater sources, which results in adverse effects. It enters the food chain and interferes with biological processes with serious physiological consequences in all living organisms, including humans. Existing removal techniques utilize different materials such as metal-organic frameworks, layered double hydroxides, ion-exchange resins, silver, polymers, bismuth, carbon, soil, MXenes, and magnetic-based materials. From our literature survey, it was clear that absorption techniques are the most frequently experimented with. In this Review, we have summarized current advancements in the removal of iodine and iodide from human-made contaminated aqueous waste.
以碘离子（I⁻）形式存在的碘（I）是人体必需的化学元素。碘是一种非金属元素，在元素周期表中属于第VIIA族（卤素）。在过去几个世纪里，工业化引发的人类社会指数级增长与碘在包括化学和生物过程在内的各种应用中的使用同时出现。然而，通过这些过程，过量的碘最终会污染土壤、地下水和淡水源，从而产生不利影响。它进入食物链并干扰生物过程，对包括人类在内的所有生物造成严重的生理后果。现有的去除技术使用不同的材料，如金属有机框架、层状双氢氧化物、离子交换树脂、银、聚合物、铋、碳、土壤、MXenes和磁性材料。从我们的文献调查来看，很明显吸附技术是实验最为频繁的。在本综述中，我们总结了从人造污染含水废物中去除碘和碘化物的当前进展。
