Title: Photocatalytic Degradation of Azo Dye using Ferric Oxide Nanoparticle
Abstract: The growth of the world population, the development of various industries and the use of fertilizers and pesticides in modern agriculture have overloaded not only the water resources but also the atmosphere and the soil with pollutants. Textile industry which is one of the largest water consumer in the world, produces wastewater comprising of various recalcitrant agents such as dye, sizing agents and dying aid. Therefore utmost care has to be taken in releasing these types of wastewater to the environment. In disposal of wastewater, color is very important due to aesthetic deterioration as well as the abstruction of penetration of dissolved oxygen and sunlight to natural water bodies. The sunlight penetration and reduction of dissolved oxygen into natural water sources affects the aquatic life. The dye precursors and the degradation products of the dye are proven to be carcinogenic in nature. Catalysts are used to convert environmentally hazardous materials into harmless compounds. In the present work ferric oxide nanoprticles are used for the photocatalytic degradation of azo dye. The influence of hydrogen peroxide and the effect of various photocatalysts on photocatalytic degradation was carried out.
