Fabrication of graphitic carbon nitride by starch and V۲O۵ for the treatment of industries effluent

The V-doped on starch/graphitic carbon nitride was synthesized for the removal of MB as an organic pollutant in industries effluent. This novel photocatalyst was illustrated by various techniques including Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), and Scanning Electron Microscopy (SEM) analysis. The RSM-CCD design was used to determine the important factor and their interactions. According to the results, the best percentage for MB removal was obtained at pH of ۹.۴, ۰.۰۸۸ of adsorbent dose, ۱۲ ppm MB concentration, ۱۹۴.۵۲ min, and ۴۰.۵۶ œC. After the adsorption, the photocatalytic activity of V-doped on starch/graphitic carbon nitride was considered at optimum condition under Ultraviolet (UV) irradiation. Finally, the findings were investigated, that the as-prepared composite can be employed for the removal of MB dye with ۸۹ % yield. The advantage of V-doped on starch/graphitic carbon nitride is the use of natural and ecofriendly materials for the pollutant removal.
