Abstract
U radu je provedena sinteza nanokompozita polipirol/cinkov oksid (PPy/ZnO), a reakcije polimerizacije monomera pirola u prisutnosti ZnO bile su različite duljine trajanja (90, 180 i 270 minuta). Cilj rada bio je dobiti optimalnu količinu vodljivog polimera u kompozitnom materijalu koja će, u kombinaciji sa ZnO, omogućiti učinkovitu razgradnju organskih onečišćenja u vodi kako bi ih preveli u biorazgradljive spojeve ili ih u potpunosti mineralizirali. Djelotvornost vodljivih polimernih kompozitnih fotokatalizatora PPy/ZnO ispitana je tijekom fotokatalitičke razgradnje organskog azobojila Reactive Red 45 na UV-A svjetlu. Metode koje su korištene za karakterizaciju kompozita PPy/ZnO bile su: FTIR spektroskopija, UV/Vis spektroskopija i pretražna elektronska mikroskopija (SEM). Uzorcima je određena i elektrovodljivost. Iz rezultata je vidljivo da je u procesu razgradnje bojila Reactive Red 45 najučinkovitiji uzorak PPy/ZnO sintetiziran 90 min.
Abstract (english)
This work involves a synthesis of polypyrrole/zinc oxide (PPy/ZnO) nanocomposites. Composites synthesis was carried out during a process of monomer pyrrole polymerization in the presence of ZnO with different polymerization time (90, 180 and 270 minutes). The aim of the work was to get the optimal content of conductive polymer in the composite material which, in a combination with ZnO, will enable effective degradation of organic pollutants in water to make them biodegradable or completely mineralized. The effectiveness of conductive polymer composite photocatalyst PPy/ZnO is tested for photocatalytic decomposition of organic azo dye Reactive Red 45 under UV-A light. Methods used for characterization of PPy/ZnO composites were: FTIR spectroscopy, UV/Vis spectroscopy and scanning electron microscopy (SEM). The electroconductivity of the samples was also determined. The results show that in the process of Reactive Red 45 degradation the most effective photocatalyst is PPy/ZnO composite synthesized for 90 min.
