Background: Electro-oxidation is developed as an electrochemical method to overcome the problems of  the conventional  decolorization technologies and is an appropriate alternative for the treatment of colored wastewater from various industries. The purpose of this study was to evaluate the efficiency of the electrochemical oxidation process in  removal  of chemical oxygen demand (COD) and Acid...

Carbamazepine is one of the hydrophilic compounds identified in aquatic environments. Due to toxicity and bio-stability of this psychotropic pharmaceutical in the environment and humans, its removal efficiency and mineralization are important. In this study, synthesized Fe@Fe2O3 nanowires were applied to improve Fenton oxidation process using FeCl3.6H2</sub...

Ammonia oxidation is an important process for decreasing ammonia concentrations in wastewater-impacted rivers. Ammonia-oxidizing bacteria (AOB) and archaea (AOA) are re sponsible for ammonia oxidation, which is the first step of the nitrification process. Nitrification and urea hydrolysis were monitored in sediment and water column samples in the Grand River (Ontario), and nitrification inhibit...

The oxidation process is one of the most important natural processes. Oxidative change in hypersensitivity is believed to be an important process in the pathogenesis. However, the clear explanation on the transmembrane flux change ofbasophil and its correlation to hypersensitivity pathogenesis has never been reported. Here, the author determines the transmembrane oxidation flux in basophil. The...

The oxidation process is one of the most important natural processes. Oxidative change in retina is believed to be an important process in the pathogenesis of diabetic retinopathy. In the present study, the oxidation flux change was assessed in such cases. The simulation test to determine the oxidation flux change based on nanomedicine technique was used. Of interest, no flux change could be de...

Oxidation of aqueous ∼8 nm unprotected copper nanoparticles takes place under air in approximately 2 hours at 30 °C to give Cu(2+) as a final product through an intermediate Cu(+) species. At 5 °C the process is about 5 times slower; similarly, vitamin C, which plays a sacrificial role, also slows down the oxidation, while CuNP catalyses the oxidation. In this work, we present a detailed analys...

Conventionally, methane is reformed into syngas, and subsequently converted into C1-oxygenates (methanol and formaldehyde). A novel option is the catalyst-free single-step conversion of methane to C1-oxygenates. This study presents a comprehensive model of methane partial oxidation to formaldehyde as an intermediate chemical species in methane oxidation process using microreactor. The dependenc...

The oxidation of ferrous iron (Fe2+) in solution using Acidithiobacillus ferrooxidans has industrial applications exclusively in the regeneration of ferric iron (Fe3+) as an oxidizing agent for the removal of hydrogen sulfide from waste gases, desulfurization of coal, leaching of non-ferrous metallic sulfides and treatment of acid mine drainage. The aim of this investigation was to increase the...
