Abstract
Global efforts are being made to find a solution to the problem of industrial waste accumulation. When dyes are introduced into natural water reservoirs, they have a detrimental influence on the ecology. Dye removal from wastewater streams is crucial. Semiconductors are typically used to convert organic contaminants in wastewater into nontoxic inorganic compounds. This contamination attempt is currently a severe concern of public health. Decolorizing and photoctlytic degradation of textile dye in the industry effluent also helps the environment from this wastes, since textile industries are characterized chemically and water-demanding, leading in greater pollution levels and water consumption. In this work the azo Acid blue AB- 113 dye was removed using irradiation as an illumination source, and UV was utilized to show the photocatalysis process. Photocatalyst activity was evaluated to remove AB-113 dye in an aqueous solution. Three experimental factors, including pH photodegradation, dye concentration, and catalyst dose, were examined for their effects on AB - 113 removals. 97% of the dye was removed by employing a catalyst dose of 0.5 gm, an initial dye concentration of 25 mg/L, and a pH of 6.2 The photodegradation of AB – 113 adsorptions on nanocomposite ZnS over the TiO2 surface may be explained kinetically using pseudo-second-order and modified Freundlich models.
