To solve the environmental challenge of textile wastewater, a UV/ZnO photocatalytic system was proposed.
The objective of this study was to prepare a photocatalytic system by utilizing both cold cathode fluorescent light (CCFL) UV irradiation and steel mesh supported ZnO nanoparticles in a closed reactor for the degradation of azo dye C.I.
Orange G (OG).
Various operating parameters such as reaction time, preparation temperature, mixing speed, ZnO dosage, UV intensity, pH, initial dye concentration, and service duration were studied.
Results presented efficient color and total organic carbon (TOC) removal of the OG azo dye by the designed photocatalytic system.
The optimal ZnO dosage for color removal was 60 g m−2.
An alkaline pH of 11.0 was sufficient for photocatalytic decolorization and mineralization.
The rate of color removal decreased with the increase in the initial dye concentration.
However, the rate of color removal increased with the increase in the UV intensity.
The steel mesh supported ZnO can be used repeatedly over 10 times without losing the color removal efficiency for 120 min reaction time.
Results of Fourier transform infrared (FTIR) and ion chromatography (IC) indicated the breakage of N=N bonds and formation of sulfate, nitrate, and nitrite as the major and minor products.
The observation indicated degradation of dye molecules.
