In this study, the degradation and mineralization of petrochemical wastewater containing phenol and nitrophenol with chemical oxygen demand (COD) at 260 mg/L and total organic carbon (TOC) at 100 mg/L, were investigated by Sono–photo-Fenton process. The full factorial design of experiment was used to explore the influence of operational variables such as pH, initial concentration of hydrogen […]
In this study, removal of m-cresol has been performed using photoeletrocatalysis technique at the surface of titanium dioxide (TiO2) thin film-modified carbon sheet photoelectrode. A biased potential was applied across this photoelectrode illuminated by UV light to investigate the feasibility of an electrochemically assisted photocatalytic process in this degradation. For preparation of this photoelectrode, the […]
ZnMnO3/Fe3O4 magnetic nanocomposites were fabricated via facile co-precipitation route and were calcined at 400 °C for 3 h. Synthesis of ZnMnO3/Fe3O4 magnetic nanocomposites were optimized by different weight percentages. Then, the as-synthesized sample was characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), photoluminescence(PL), vibrating Sample Magnetometer (VSM), EDAX (Energy dispersive X-ray analysis), diffuse reflectance UV–Vis spectroscopy […]
Preparation and application of CoMgAl-hydrotalcites have been studied. In this paper CoMgAl-LDHs photocatalysts were prepared by co-precipitation. Various techniques such as UV–visible spectrometry (UV–vis), BET, differential thermal gravimetric analysis, scanning electron microscopy analysis and X-ray diffraction were used to investigate the catalytic activity, structure, and composition of the prepared samples. The photocatalysts were developed as […]
Aniline is used by many industrial organizations and is released into the environment in high amounts and pollutes the water. Due to the damages to human health, there is a need for effective and environmentally friendly methods to remove this compound from the water. The aim of this work is to mineralize and remove aniline […]
By nthesizing nano zinc oxide with different morphologies, such as spherical, snowflake like, and starfish like, and utilizing its unique physical and chemical properties, combined with the cavitation effect of ultrasound, it is expected to achieve effective degradation of dye wastewater. In the comparative experiment of using nano zinc oxide, ultrasound, ultrasound+nano zinc oxide to […]
