The electrochemical advanced oxidation method “Electro-Fenton” has been applied to remove 17β-estradiol (17β) estra-1,3,5(10)-triéne-3,17-diol) in aqueous-acetonitrile mixture. This endocrine disrupting is a steroid hormone, releases from humans, animals and residual pharmaceuticals into the environmental water and usually causes suspected undesirable effects in aquatic organisms. The degradati...
Background and Objectives: Ciprofloxacin is an emerging and degradable pollutant that cannot be efficiently removed by common water and wastewater treatment processes. Electro-Fenton process is one of the most effective processes for the treatment of these compounds. Hence, the present study aimed to remove ciprofloxacin by Electro-Fenton method with heterogeneous catalysts, Fe+2 and Fe+3. Mat...
A sequential treatment of ozonation followed by a Fenton or photo-Fenton process, using black light lamps (365 nm) in this latter case, has been applied to remove a mixture of pharmaceutical compounds and the generated by-products both in ultrapure and secondary treated wastewater. The scientifictechnological innovation of this study stems from the in situ generation of hydrogen peroxide from t...
The degradation of chlorpyrifos in water by Fenton (H2O2/Fe 2+) and solar photo-Fenton (H2O2/Fe 2+/solar light) processes was investigated. A laboratory-scale reactor was designed to evaluate and select the optimal oxidation condition. The degradation rate is strongly dependent on pH, temperature, H2O2 dosing rate, and initial concentrations of the insecticide and Fe 2+. The kinetics of organic...
An experimental study of the homogeneous Fenton and photo-Fenton degradation of 4-amidophenol (paracetamol, PCT) is presented. For all the operation conditions evaluated, PCT degradation is efficiently attained by both Fenton and photo-Fenton processes. Also, photonic efficiencies of PCT degradation and mineralization are determined under different experimental conditions, characterizing the in...
Background and purpose: Microbial electro-Fenton system as a novel technology can be employed in removal of resistant organic pollutants along with generation of renewable electrical energy through the activity of anaerobic microorganisms. This study aimed at investigating the performance of this process in treatment of synthetic wastewater containing tetracycline and generation of electricity ...
The present work investigates the conjugation of flotation and photo-Fenton techniques on oil removal performance from oilfield produced water. The experiments were conducted in a column flotation and annular lamp reactor for induced air flotation and photodegradation steps, respectively. A nonionic surfactant was used as a flotation agent. The flotation experimental data were analyzed in terms...
Oxidation of pollutants in waste water by photo-Fenton reaction has proven an ecofriendly and economical method. Oxidation of amido black – 10B, (an acid dye of azo series) using photoFenton reagent was investigated under ambient conditions. The effect of different parameters like the concentration of ferric ion, amido black10B and hydrogen peroxide, pH, light intensity etc. on the reaction rat...
background: electrochemical methods, as one of the advanced oxidation processes (aops), have recently been applied to remove different contaminants from water and wastewater. this study compares the performance of anodic oxidation (ao) and electro-fenton (ef) methods on waste sludge treatment. methods: this experimental study was performed on real sludge and the effect of operating parameters s...
