<p>The invention relates to a process for obtaining functionalized magnetic systems suitable for various environmental applications. According to the invention, the process consists in dispersing magnetite particles into a polysulphone gel having a concentration of 3...25%, into dimethylsulphone or other suitable solvent, followed by coagulation of said heterogeneous structures into a coagulation bath, wherefrom there result magnetic systems of the type FeO/functionalized polysulphone as spheres, thin films or fibres.</p> |
