Abstract :

Abstract: Aniline has high toxicity and is immediately absorbed through the skin. If aniline is swallowed or its vapor is inhaled, it will lead to death. Considering aniline risks on the environment and human health, it is necessary to prevent its spread into the environment. This study’s purpose is to remove aniline using a photocatalytic process under visible light irradiation. For this purpose, the zinc oxide was loaded with different values of reduced graphene oxide and graphene. The photocatalytic activity of modified zinc oxides (rGO/ZnO and G/ZnO) was investigated for aniline contaminant removal under visible light radiation. The physicochemical properties of zinc oxide and modified zinc oxides were analyzed by XRD, SEM, IR, PL, TEM and UV–vis (DRS mode) spectroscopy. The results showed that rGO/ZnO and G/ZnO composites had higher photocatalytic activity than ZnO, and the G(10%wt)/ZnO photocatalyst showed the highest photocatalytic activity and efficiency in removing aniline contaminant (75%).
