Özet:

 


Aim
of this study is to produce highly active hybrid propolis-TiO2
nanocomposites using sol-gel method and to use it remediation of food industry
waste. Propolis solution was prepared in ethanol and added to sol-gel mixture
at increasing volume (0.25,
0.50, 0.75, 1.00 mL) to prepare propolis-TiO2 (P-TiO2)
hybrid catalyst. Neat TiO2 was also prepared by the same sol-gel
technique and its action was compared to propolis doped ones. Catalysts were
calcinated at 300 oC to obtain desired anatase form.





After
production the catalysts were characterized by X-ray diffraction (XRD),
scanning electron microscopy (SEM) and FTIR. Sunset Yellow (SY), Allura red
(AR) and Tartrazine (TT) were used as model compounds ([C]0=10 mgL-1,
catalyst mass=1 gL-1) . Concentration of dyes were monitored by
UV-vis spectrometry. P-TiO2 catalyst prepared with 1.00 mL propolis solution
was extremely effective for removal of all dyes studies for both 254 nm and 365
nm light exposure. LED light exposure provided lower removal rate (approx..
25%) but it was still significant for dye removal.
