Beschreibung
Zusammenfassung:	The invention relates to magnetic nanostructures based on polymer functionalized with chelating agents, used as adsorption materials for removing pollutants from water and soil and to a process for preparing the same. According to the invention, the nanostructures are based on poly(benzofurane-co-arylacetic acid) functionalized with chelating agents (dopamine/Nα, Nα-bis(carboxymethyl) -L-lysine). The claimed process consists of two reaction stages carried out in reflux conditions, without addition of catalysts: the opening of the lactonic cycle, present in the polymer structure, by the free amino groups, present in the structure of the chelating agents, and the adsorption of the functionalized polymers on the surface of the magnetic nanoparticles.
