Although there has been a great deal of research on the structure and function of echolocation calls used for foraging and commuting, relatively little research has been conducted on the communication functions of bat vocalizations (Pfalzer and Kusch, 2003). In addition to echolocation calls, bats produce social calls which differ from echolocation calls in structure and function (Fenton, 2003)...

Three carbon materials from a varied origin, composition and porosity have been used as cost-effective cathodes in different electrochemical advanced oxidation processes (i.e. anodic (AO) electro-Fenton (EF) homogeneous heterogeneous catalysis modalities) for the degradation of an antibiotic (e.g., metronidazole). In general, efficiency towards pollutant increased as: AO < EF EF. The approach w...

The Photo-Fenton reaction is an advanced technology to eliminate organic pollutants in environmental chemistry. Moreover, the conversion rate of Fe(3+)/Fe(2+) and utilization rate of H2O2 are significant factors in Photo-Fenton reaction. In this work, we reported three dimensional (3D) hierarchical cobalt ferrite/graphene aerogels (CoFe2O4/GAs) composites by the in situ growing CoFe2O4 crystal ...

Pesticide wastewater has the characteristics of high organic pollutant, high concentration, deep color and high toxicity, which has become difficult to treat the organic wastewater with high concentration at home and abroad. This article uses three methods of US(ultrasonic), Fenton(Fe&H2O2) and combination of US&Fenton were used in the comparative research on the treatment of organic pesticide ...

The applicability of Fenton and photo-Fenton processes as a pretreatment stage to combined wastewater was investigated. The wastewater was obtained from the inlet of the aeration tank in 42 Evler industrial and domestic wastewater treatment plant. The effects of different process variables such as initial Fe2 (c0 8 33 mmol L –1) and H2O2 (c0 65 165 mmol L –1) concentrations, pH (3 7.75) and rea...

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...

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...
