Abstract

The present invention belongs to the field of procedures for the removal of oily stains from the water, more precisely to the field of preparation procedures of superparamagnetic adsorptive nanomaterials based on iron oxide nanoparticles. Preparation process of functionalized superparamagnetic adsorbents with diphenyldimethoxysilane (DPDMS) as precursor allows preparation of adsorbents which enable adsorption of oil stains with a capacity in the range 2.0 to 4.0 g of oil/g of adsorbent, and nanostructured core based on iron oxide nanoparticles CoFe<2>O<4>with spinel crystal structure, enabling responsiveness and maneuverability of nanostructures under the influence of an external magnetic field and further, via the functionality of the surface, adsorption and removing of oil stains, recovery and re-use.
