Abstract
In this research, a Polycyclic Aromatic Hydrocarbons (PAHs) is studied,
which is Naphthalene (NAP) and an organic compound with the formula C ₁₀H ₈. It
is a polycyclic aromatic hydrocarbon, which is a crystalline substance with a
characteristic odor in various sources of wastewater and treatment by catalyzing
and activating ZnO/TiO2/H2O2 catalysis under
the influence of the same ultraviolet radiation. Eleven wastewater sources were
collected from different industrial wastewater and treated wastewater (5 Farms,
Main treatment plant, Tanning factory treated wastewater, Tanning factory
non-treated wastewater, Carton factories, Factories Lake, and Grease refining
plants. Water samples were extracted by QuEChERS methodology and analyzed by
GCMSMS/TQD by GCMSMS/TQD with curing techniques using different wavelengths of
ultraviolet radiation UV were applied to Naphthalene (NAP) particles under two
wavelengths (254 and 306 µm) using H2O2 catalyst for 8 hours. The effect of
multiple curing times of photosensitizers containing naphthalene was also
studied. The results obtained in this research indicate that the NAP detection
limit was µg/L, and the concentration was between 96-99%. The impact of
photocatalysis on the NAP compound disappeared after 3 and 4 hours of treatment
using 306 µm after UV radiation with a ZnO/TiO2/H2O2
catalysis, generally appropriate, the results of the photo treatment were
effective and sufficient to break down the NAPH compound. Conductive
electronics, which react with the oxygen adsorbed on the surface to give
superoxide radical anions, and finally, produce water starting from HO • This
dose oxidizes the target molecule with NAPH to anthraquinone and thus this
treatment method can be used to treat contaminated water with NAP, which can be
maintaining water sustainability and its variability of reuses.
