Abstract :
Different antibiotic drugs are widely present in the environment for
the treatment of bacterial infections. Overuse of antibiotics leads to the
accumulation of these drugs in water systems. Removing antibiotics-based
pollutants from water is essential. Nanoscience and nanotechnology can
be very helpful in this field. In this work, CuO/ZrO2 nanocomposites was
prepared via the simple and facile method. The prepared samples were
analyzed X-ray diffraction (XRD), transmission electron microscopy
(TEM), scanning electron microscopy (SEM), energy-dispersive X-ray
spectroscopy (EDS), Fourier-transform infrared spectroscopy (FTIR)
analysis, and UV-Vis analysis. The results indicate the high potential of
synthesized nanocomposites made in photocatalytic degradation. The
prepared CuO/ZrO2 Nanocomposites degrades 96.4% of Tetracycline
antibiotic under ultraviolet light irradiation after 120 min. The effect of
CuO/ZrO2 nanocomposites dosage and solution pH was studied. It was
found that the photocatalytic performance of CuO/ZrO2 nanocomposites
can be improved via increasing concentration until optimal dosage (0.8
g/L) and in a higher dosage than 0.8 g/L no significant improvement
was observed. Also, the results confirmed that the photodegradation of
tetracycline can be elevated via increasing pH.
