Abstract

In this paper, α-Fe₂O₃/NiS has been synthesized as a Photocatalyst for Removal of Alizarin red-S from Aqueous Solution. The as-prepared sample were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform infrared spectra (FTIR). Then photocatalytic degradation was carried out in the presence of the α-Fe₂O₃/NiS on Alizarin red-S. The effect of catalyst dose, pH and initial dye concentration on the degradation process has been assessed. Different concentrations of α-Fe₂O₃/NiS photocatalyst (0.25, 0.50, 0.75, 1.0, 1.25, 1.5, 1.75and 2g/L), different pH values (1-10) and different concentrations of dye (10-100 ppm) were employed for the present study.
