During recent years, many advanced oxidation techniques have been investigated for water and wastewater treatment to overcome the shortage of clean water. This review summarizes the background and principles of photocatalysis applied as an advanced oxidation technology. In particular, this paper focuses on modification of photocatalysts with various dopants as well as the novel photocatalytic r...

This study presents a review on advanced oxidation processes (AOP) for simultaneous removal of NO and SO2. AOP is based on using a strong oxidant such as ozone and H2O2 which is able to generate highly reactive intermediates. The pollutant will be oxidized and removed by these intermediates. In recent years, AOP has been considered as an effective and attractive technology in the field of flue ...

background: the aim of this study was to measure the concentrations (levels) of serum total proteins and advanced oxidation protein products as markers of oxidant mediated protein damage in the sera of patients with oral cancers. methods: the study consisted of the sera analyses of serum total protein and advanced oxidation protein products’ levels in 30 age and sex matched controls, 60 patient...

chemical oxidation is one of the most suitable treatment methods for reducing organic pollutants and the number of pathogens remaining in secondary effluents. ozone is the most powerful oxidizing agent commonly used because of it's many advantages over chlorination. in this study the efficiency of ozonation in advanced wastewater treatment of sahebgharanieh plant has been determined. ozone gene...

this study was aimed at investigating the photocatalytic degradation of ciprofloxacin (cip) antibiotic in aqueous solution using immobilized zno nanoparticles on glass plate. x-ray diffraction, atomic force microscopy, and scanning electron microscopy were applied to characterize the nanoparticles. to do so, the zno nanoparticles were synthesized through the chemical precipitation method and we...

 Nowadays, underground water is the main source of drinking water that contamination to organic pollutants such as MTBE is an important issue. One of the suitable methods for these types of pollutants is the advanced oxidation methods. Advanced oxidation processes (AOPs) are involved in the production of highly reactive hydroxyl radicals that oxidize organic matter such as MTBE and even le...

background: the purpose of the present study was to assess the efficiency of ultrasound/hydrogen peroxide processes and ultrasound/hydrogen peroxide/zno nanoparticles in the removal of blue cat 41 dye from aqueous solutions. methods: zno nanoparticles were prepared using the hydrothermal method. variables including ph, concentration of zno nanoparticles, initial dye concentration, concentration...
