Photocatalyst based on TiO2 and its application in organic wastewater treatment using simple spray method

Abstract

In present research, we reported a successfully coating of TiO2 particle on the transparent plastic applied for photocatalyst process by spray method. This method was employed to degrade organic wastewater (Methylene Blue) under solar exposure. A total of 300 ml of blue methylene was used in the photocatalyst test. From the absorbance spectrum and the degradation rate of methylene blue, it is confirmed that the methylene blue successfully degraded about 98% in 16 hours of irradiation. The result suggests a faster rate of degradation than previously reported studies. This method was selected due to its simplicity, environmentally friendly, reasonably priced, and has the potential to continue to be developed further.
