Abstract

The importance of nanotechnology in protecting the environment is represented in multiple applications, including, for example, the green synthesis of nanoparticles (NPs), using the remains of plant parts, as well as photolysis application that used semiconductors NPs which showed a clear effect in treating water from organic pollutants, this study combines these two applications, in terms of green synthesis of titanium dioxide nanoparticles (TiO2NPs) using melon peel (Cucumis melo L.) in sol-gel method, as well as, the photodegradation of methylene blue dye (MB) by using a new irradiation photoreactor device which has designed and implemented for this purpose. This device used to irradiate MB dye with three different types of ultraviolet$-$visible (UV) light sources to study the photodegradation with different cases, first on circulation of MB dye only, second when irradiation MB dye with UV-A, UV-B, UV-C light sources with circulation, finally, the effect of adding (0.05 g) of green synthesized of TiO2NPs by using melon peel extract in sol-gel method with irradiation and circulation MB dye in the system. Different percentage of MB dye removal where reported. The prepared of TiO2NPs catalysts were characterized using, Energy dispersive analysis (EDX), Ultraviolet$-$visible spectroscopy (UV-Vis), Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray spectroscopy (XRD), Atomic force microscopy (AFM). High performance of photodegradation was absorbed under UV-C, UV-B irradiation of MB dye in 90 min.
