The simple photo-batch reactor was used to investigate the degradation of MNZ under the effect of UV radiation, initial concentration of MNZ, pH, catalyst loading, inorganic salts addition, time, and temperature.Results: The degradation efficiency is mainly divided into two steps: 35.7% for maximum adsorption and 57.5% for photodegradation.

Adsorption constant during dark condition is smaller than typical adsorption equilibrium constant derived from the Langmuir–Hinshelwood kinetic model through photodegradation of MNZ that follows pseudo-first-order kinetics. Toxicity rates were reduced considerably after the photodegradation process to 88.21%, 79.84%, and 67.32% and 57.45%, 51.98%, and 43.87% by heamolytic and brine shrimp assays, respectively, for initial MNZ concentrations (20, 60, and 100 mg/L).Conclusion: We significantly recommend using MgO NP as a promising catalyst in the photodegradation applications for other organic pollutants in visible light.Keywords: adsorption, Langmuir, magnesium oxide nanoparticles, metronidazole, photodegradation, toxicityEl Bouraie MIbrahim SDove Medical Pressarticleadsorptionlangmuirmagnesium oxide nanoparticlesmetronidazolephotodegradationtoxicityMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 15, Pp 7117-7141 (2020)
