Researchers from the Institute of Materials Science of Madrid, belonging to the Superior Council of Scientific Research (ICMM-CSIC), developed magnetic nanoflowers made of iron oxide. These nanometric structures were specifically designed to interact with nanoplastics present in aqueous media.
The magnetic nanoflowers demonstrated the ability to effectively capture PET (polyethylene terephthalate) nanoplastics, one of the most common types of plastic in aquatic environments. After capture, the researchers managed to transform these materials into a new type of material with useful properties for water treatment.
The developed process allows converting the captured nanoplastics into functional materials capable of removing pollutants from water. This approach represents a solution that combines the decontamination of water resources with the valorization of plastic waste.
The researchers highlight that this technology promotes the circular economy, by transforming an environmental pollutant into a useful resource. The work constitutes a significant advance in combating nanoplastics contamination, which represents a growing challenge for the environment and public health.
