This study aimed to assess, optimize and model the efficiencies of Fenton, photo-Fenton ozonation/Fenton processes in formaldehyde elimination from water wastewater using response surface methodology (RSM) artificial neural network (ANN). A sensitivity analysis was used determine importance independent variables. The influences different variables, including H2O2 concentration, initial Fe dosag...

Several homogeneous photo-based advanced oxidation processes-namely photolysis, photo-oxidation, and photo-Fenton oxidation—were investigated for the elimination of ibuprofen in water. The effects several operating parameters, such as lamp type (low or medium pressure mercury, xenon-arc), concentration hydrogen peroxide (0.5 to 7 times stoichiometric amount required mineralization), Fenton reag...

This study investigated the reduction of the chemical oxygen demand from the Kermanshah oil refinery wastewater using Fenton and Photo-Fenton processes. The study investigated the effects of operating variables such as ultraviolet light intensity in values of 0, 15, and 30 W, ferrous ion concentration in values of 10, 50, and 90 mg/l, hydrogen peroxide concentration in values of 100, 500 and, 9...

background : airborne particulate matter is one of the most important atmospheric pollutants. tile sources of particulate matter in the atmosphere are divided into two groups; 1) natural sources and 2) anthropogenic sources. the important components of airborne particulate matter and invarying concentrations are the ubiquitous components of the lower atmosphere. heavy metals are mainly emitted ...

The mineralisation of remazol black B (RBB) was studied at concentrations ranging from 20-1000 mgL(-1). The work was aimed at investigating the Fenton-like peroxidation of RBB at a concentration typically obtained in Batik cottage industries. Other response parameters were degradation and colour removal efficiencies. The parameters that were measured included total organic carbon (TOC), chemica...

AIMS To provide common Organic Chemistry/Polymer Science thermoset free-radical crosslinking Sciences for Medical understanding and also present research findings for several common vitamins/antioxidants with a new class of drugs known as free-radical inhibitors. STUDY DESIGN Peroxide/Fenton transition-metal redox couples that generate free radicals were combined with unsaturated lipid oils t...

H2O2 mimicked the action of periportal pO2 in the modulation by O2 of the glucagon-dependent activation of the phosphoenolpyruvate carboxykinase (PCK) gene and the insulin-dependent activation of the glucokinase (GK) gene. H2O2 can be converted in the presence of Fe2+ in a Fenton reaction into hydroxyl anions and hydroxyl radicals (.OH). The hydroxyl radicals are highly reactive and might inter...
