Abstract:Magistrsko delo zajema sinteze magnetnih nanodelcev in sinteze magnetno zeolitnih nanokompozitov. Magnetni nanodelci so bili sintetizirani z metodo koprecipitacije oz. s soobarjalno metodo in mikrovalovno metodo. Magnetno zeolitni nankompoziti so nastali z naknadno sintezo in sočasno sintezo. Dobljeni produkti so bili okarakterizirani s Fourierjevo transformirano infrardečo spektroskopijo na oslabljen totalni odboj (ATR-FTIR), termogravimetrično analizo (TGA), dinamičnim sipanjem svetlobe (DLS), Brunauer-Emmett-Tellerjevo metodo (BET), vrstičnim elektronskim mikroskopom (SEM) in rentgensko praškovno difrakcijo (RTG). Rezultati karakterizacijskih metod so pokazali, da je bila uspešnejša sinteza magnetno zeolitnega nanokompozita z naknadno sintezo tako pri soobarjalnih magnetnih nanodelcih kot tudi pri mikrovalovnih. Sintetizirani magnetni nanodelci in nanokompoziti so bili nato še uporabljeni za odstranjevanje mikro in nanoplastike iz vode. Odstranjevanje je potekalo s pomočjo ultrazvočne kopeli in posedanjem na magnetu iz modelne raztopine polietilena. UV/VIS spektroskopija je pokazala, da je bilo najuspešnejše odstranjevanje z magnetnimi nanodelci sintetiziranimi s soobarjalno sintezo.

Title:Synthesis of magnetic zeolite nanocomposite
Abstract:This master thesis covers the synthesis of magnetic nanoparticles and the synthesis of magnetic zeolite nanocomposites. Magnetic nanoparticles were synthesized by the method of coprecipitation method and the microwave method. Magnetic zeolite nanocomposites were formed by subsequent and simultaneously synthesis. The obtained products were characterized by attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), thermogravimetric analysis (TGA), dynamic light scattering (DLS), Brunauer-Emmett-Teller method (BET), scanning electron microscopy (SEM) and X-ray powder diffraction (XRD). The results of the characterization methods showed that the synthesis of the magnetic zeolite nanocomposite was more successful with subsequent synthesis both with co-precipitation of magnetic nanoparticles and with microwaves. The synthesized magnetic nanoparticles and nanocomposites were then used to remove micro and nanoplastics from water. The removal took place with the help of an ultrasonic bath and sitting on a magnet made of a polyethylene (PE) model solution. UV/VIS spectroscopy showed that the most successful removal by magnetic nanoparticles was synthesized by coprecipitation.
