Abstract

The aim of present study was to fabricate zinc oxide nanoparticles (ZnO NPs) from facile and green route for wastewater treatment. Purity and crystalline character of synthesized nanoparticles from seeds extract of citrus lemon were investigated by X-ray diffraction. The average crystalline size of ZnO Nps was calculated as 51.68 nm using Debye–Scherrer formula, while the lattice parameters (a = 3.32 and c = 4.56) were calculated using cell software, while calculated volume of the unit cell for hexagonal symmetry was 8.68 Å3. The particle size, morphology and elemental composition of biosynthesized nanoparticles were confirmed by scanning electron microscope and energy-dispersive X-ray spectroscopy, respectively. The photocatalytic activity of the synthesized nanoparticles was examined by degradation of remazol brilliant blue, a textile dye under UV light irradiation. Maximum degradation of remazol brilliant blue was found to be 85.91% after only 60 min of incubation. ZnO Nps retained its activity after five washings and therefore can be recycled and reused. Furthermore, it is concluded and recommended that ZnO Nps synthesized from green route should be the best economical alternate for textile effluent treatment
