Matrix Effects of Different Water Types on the Efficiency of Fumonisin B1 Removal by Photolysis and Photocatalysis Using Ternary- and Binary-Structured ZnO-Based Nanocrystallites

Several ternary- and binary-structured ZnO-based nanocrystallites (Zn2SnO4, Zn2TiO4, ZnO/SnO2, ZnO/TiO2) were synthesized by the solid-state method first tested as photocatalysts in removal of fumonisin B1 (FB1) under UV irradiation. The phase composition nanocrystalline dimensions (50–80 nm) confirmed X-ray diffraction Raman analyses. Similar preparation procedures applied case binary structures resulted their uniform morphology consisting spherical particles ranging from 100 nm to 1 µm size. However, higher synthesis temperatures ternary oxides contributed growth up 10 µm. optical energy bands examined range 3.08–3.36 eV. efficiency photocatalysis was compared with direct indirect (sensitized UV/H2O2 or UV/S2O82−) photolysis. matrix effect different water types (Danube River, ground, tap water) on FB1 investigated applying photolysis, well presence Zn2SnO4 photocatalyst. effects inorganic anions (Cl−, NO3−, HCO3− SO42−), cations (Ca2+ Mg2+), humic acid also investigated, since they identified a major species tap, river water.
