| Abstract | In the present study, iron nanoparticles (Fe-NPs) were synthesized using extracts of green tea leaves as reducing andcapping agents under atmospheric conditions. The Fe-NPs were characterized using scanning electron microscopy, energydispersive spectrometry, transmission electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy. Thenanoparticles were mostly spherical and uniform in size with diameters that ranged from 50 to 70 nm and then used as a Fentonlike catalyst for the decolorization of direct scarlet 4BS in solution. About 85% of the dye was successfully removed in 30 minusing 1 g/L of catalyst in the presence of 15 mM of H2O2 at low (acidic) pH values of 2?4 at room temperature. |
