Procedure of preparation of functionalized superparamagnetic adsorbents with dimethyldichlorosilane (DMDCLS) precursor

Predmet izuma sodi v področje postopkov za odstranjevanje oljnih madežev iz voda, bolj natančno v področje postopkov priprave superparamagnetnih adsorpcijskih nanomaterialov na osnovi nanodelcev železovega oksida. Postopek priprave funkcionaliziranih superparamagnetnih adsorbentov s prekurzorjem dimetildiklorosilan (DMDCLS) omogoča adsorpcijo oljnih madežev s kapaciteto v območju 2,0 - 4,0 g olja/g adsorbenta, in nanostrukturnim jedrom na osnovi nanodelcev železovega oksida CoFe2O4 spinelne kristalne strukture, ki omogočajo odzivnost in vodljivost nanostrukture pod vplivom zunanjega magnetnega polja ter vsled funkcionalnosti površine tudi vezavo in odstranjevanje oljnih madežev, regeneracijo in ponovno uporabo. The present invention belongs to the field of procedures for the removal of oily stains from the water, more precisely to field of preparation procedures of superparamagnetic adsorptive nanomaterials based on iron oxide nanoparticles. Preparation process of functionalized superparamagnetic adsorbents with dimethyldichlorosilane (DMDCLS) 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.
