Abstract :
Aniline is one of the simplest aromatic amine compounds, which is highly toxic. The aniline inhalation causes inflammation of the lungs and in high concentrations, eating or inhaling its vapor is fatal. The aim of the present study is to remove aniline by photocatalytic process with copper sulfide under visible light radiation. First, the effect of the type of copper and sulfur precursors in the synthesis of copper sulfide was investigated. Next, in order to create magnetic property in the photocatalyst and to easily separate it from the suspension by magnet, composites with different ratios of copper sulfide and magnetic Fe3O4 were prepared. The X-ray diffraction, scanning electron microscope and ultraviolet-visible emission reflection spectroscopy were used to survey the physical and chemical properties of the synthesized samples. The results revealed that copper sulfide synthesized with copper acetate and thioacetamide shows the highest photocatalytic activity compared to copper sulfides synthesized with other precursors. Also, by adding Fe3O4 to copper sulfide, in addition to creating magnetic property, the performance of photocatalysis and the percentage of aniline removal also increases.
