FABRICATION OF IRON DOPED COBALT OXIDE GRAFTED ON GRAVEL AND ITS APPLICATIONS IN INDUSTRIAL WASTEWATER TREATMENT

Abstract

Wastewater has numerous detrimental influences on aquatic life due to manifestation of poisonous, heavy metals and other poisonous organic compounds. Organic micropollutants in aqueous medium can be despoiled by heterogenous photocatalysis. Therefore, present research will be intensive on the synthesis and usage of iron-doped cobalt oxide to remediate the dyes in wastewater. Iron doped cobalt oxide will be grafted on gravel by spray pyrolysis method. Iron-doped cobalt oxide will be characterized by X-ray diffraction, Fourier transform infrared spectroscopy, energy dispersive X-ray and scanning electron microscopy. Response surface methodology will be active to improve the operational parameters like concentration of hydrogen peroxide, irradiation time, pH and initial concentration of wastewater. Rate of photocatalytic deficiency of textile wastewater will be observed under optimized conditions by Fourier transform infrared spectroscopy and UV/Visible spectrophotometry. Water quality factors like BOD, COD and TOC will be examined before and after the photocatalytic treatment. Moreover, reusability of iron doped cobalt oxide will also be checked.
