Abstract
Čestice željezovih oksida mogu se pripraviti različitim metodama, najčešće korištena metoda je hidrotermička mikrovalna sinteza. Najveća prednost ove metode je mogućnost preciznog kontroliranja uvjeta sinteze. Ovaj rad daje kratki uvid u proces hidrotermičke mikrovalne sinteze čestica te je istražen utjecaj dodatka biljnih ekstrakata kamilice i brnistre na sintetizirane čestice hematita prije i nakon postupka sušenja. Sinteze su rađene pri temperaturi od 200 °C u trajanju od 20 minuta te su sintetizirane čestice čistog hematita. Dodatkom ekstrakata brnistre i kamilice prije postupka sušenja dokazan je nastanak smjese hematita i getita, dok dodatak ekstrakata nakon sušenja nije imao utjecaja na produkt sinteze. Dobivene čestice karakterizirane su infracrvenom spektroskopijom sa Fourierovom transformacijom (engl. Fourier Transform Infrared Spectroscopy, FTIR).
Abstract (english)
Iron oxide particles can be prepared by different methods, but the most commonly used method is hydrothermal microwave synthesis. The main advantage of this method is the possibility to precisely control the synthesis conditions. This thesis gives a brief insight into the process of hydrothermal microwave particle synthesis. In addition, the influence of the chamomile and broom plant extracts on the synthesized particles before and after the drying process was investigated. The syntheses were carried out at a temperature of 200 °C for 20 minutes, and the synthesized particles were pure hematite. With the addition of broom and chamomile extracts before the drying process the formation of a mixture of hematite and goethite was proved, while the addition of extracts after drying had no effect on the final product resulting pure hematite particles. The obtained particles were characterized by Fourier Transform Infrared Spectroscopy, FTIR.
