چکیده مقاله:
Nowadays, not only the lack of water sources but also water pollution by industrial wastewater has become a major challenge. One of the pollutants of water resources, which threatens water resources, is phenol that enters the environment through wastewater from various industries such as petrochemicals, refineries, pharmaceuticals, etc. This compound, due to its toxicity, high stability and solubility in water caused many problems and it is very important to remove it from industrial wastewater. Therefore, the main purpose of this study is to remove phenol from wastewater by using catalytic oxidation. Fe-ZSM-۵ catalyst was synthesized by precipitation method and its characteristics were determined by XRD, FTIR, SEM and BET analyses. The results of XRD analysis showed that the iron ions are in the MFI structure and the catalyst has a good crystallinity phase, so that it retains its MFI structure. BET analysis showed the specific surface area of the synthesized catalyst is ۲۹۳g/m۲. The catalytic activity of Fe-ZSM-۵ was investigated in degradation of phenol and the results showed that the mentioned catalyst had the highest removal percentage (۸۵.۸۲%) in ۹۰ min at pH = ۴.۲۵ and T= ۷۰ °C. The effect of various parameters such as ultraviolet radiation, initial pollutant concentration, catalyst loading and H۲O۲ concentration on the catalytic activity were also investigated.
