Abstract
Iodine (I-2) in the form of iodide ions (I-) is an essential chemical element in the human body.Iodine is anonmetal that belongs to the VIIA group (halogens) in the periodictable. Over the last couple of centuries, the exponential growth ofhuman society triggered by industrialization coincided with the useof iodine in a wide variety of applications, including chemical andbiological processes. However, through these processes, the excessamount of iodine eventually ends up contaminating soil, undergroundwater, and freshwater sources, which results in adverse effects. Itenters the food chain and interferes with biological processes withserious physiological consequences in all living organisms, includinghumans. Existing removal techniques utilize different materials suchas metal-organic frameworks, layered double hydroxides, ion-exchangeresins, silver, polymers, bismuth, carbon, soil, MXenes, and magnetic-basedmaterials. From our literature survey, it was clear that absorptiontechniques are the most frequently experimented with. In this Review,we have summarized current advancements in the removal of iodine andiodide from human-made contaminated aqueous waste.
