ClearMagnetic nanocomposites: innovative adsorbents for antibiotics removal from aqueous environments–a narrative review
This review examines how magnetic nanocomposite materials can be used to remove pharmaceutical pollutants from water. While not directly about microplastics, the technology is relevant because microplastics in water often carry pharmaceutical residues that conventional treatment cannot fully remove. Better water filtration methods like these could help reduce human exposure to the cocktail of pollutants that microplastics transport.
