Iron and copper toxicity has been presumed to involve the formation of hydroxyl radical ( . OH) from H2O2 in the Fenton reaction. The aim of this study was to verify that Fe 2+ -O2 and Cu + -O2 chemistry is capable of generating . OH in the quasi physiological environment of Krebs-Henseleit buffer (KH), and to compare the ability of the Fe 2+ -O2 system and of the Fenton system (Fe 2+ + H2O2) t...

BACKGROUND The oxidation of proteins by endogenously generated free radicals causes structural modifications in the molecules that lead to generation of neo-antigenic epitopes that have implications in various autoimmune disorders, including rheumatoid arthritis (RA). Collagen induced arthritis (CIA) in rodents (rats and mice) is an accepted experimental model for RA. METHODOLOGY/PRINCIPAL FI...

introduction             wastewater treatment using activated sludge process (asp) produces huge amounts of sludge that must be treated by efficient methods. wastewater sludge handling is one of the most important economic-technical challenges of wastewater treatment projects. conventional methods for this purpose are very time consuming, expensive and in lots of cases have limited success. in ...

13 Alternative conditioning of aluminium-based drinking water treatment sludge 14 using Fenton reagent (Fe 2+ /H2O2) was examined in this study. Focuses were placed on 15 effectiveness and factors to affect such novel application of Fenton process. 16 Experiments have demonstrated that considerable improvement of alum sludge 17 dewaterability evaluated by capillary suction time (CST) can be obt...

We examined the effects of ultrasound and Fenton reagent on ultrasonic coupling Fenton oxidation (U+F) pre-treatment processes for the disintegration of wastewater treatment plant sludge. The results demonstrated that U+F treatment could significantly increase soluble chemical oxygen demand (SCOD), total organic carbon (TOC), and extracellular polymeric substances (EPS) concentrations in sludge...

Presence of antibiotics in the environment may cause potential risk for aquatic environment and organisms. In this research, Fenton oxidation process was offered as an effective method for removal of antibiotic sulfamethoxazole from aqueous solutions. The experiments were performed on laboratory-scale study under complete mixing at 25±2°C. The effects of initial antibiotic concentration, molar ...

This research investigated the efficiency of Advanced Oxidation Processes, Enzymatic treatment, and combined enzymatic/AOPs sequences on color remediation of CMP pulp and paper mills effluent. Regarding enzymatic treatment two kinds of fungal enzymes; Laccase (EC: 1.10.3.2) from Terametes Versicolor and Versatile Peroxidase (EC: 1.11.1.7) from Bjerkandera adusta were chosen and applied. Also, t...

The application of the photo-Fenton process for the treatment of wastewaters contaminated with diesel oil was investigated. This particular process has been widely studied for the photochemical degradation of highly toxic organic pollutants. Experiments were performed according to a factorial experimental design at two levels and two variables: H(2)O(2) concentration (5-200 mM) and Fe(2+) conce...
