Photochemical reactions with the participation of iron(iii) carboxylates are important for environmental photochemistry and have a great potential of application in water purification (advanced oxidation processes, photo-Fenton and Fenton-like processes). In spite of this, information about excited states and primary intermediates in the photochemistry of Fe(iii) complexes with carboxylic acids...

An experimental study on 4-chlorophenol (4-CP) degradation in aqueous solutions by advanced oxidation process photo-Fenton type is presented. The efficiency of the oxidation process is determined by the very high oxidative potential of the OH. radicals generated by catalytic and photo-catalytic processes. The presence of the inorganic species inside the reaction medium influences the rate of th...

In this work, we have tested a photocatalytic material consisting of core SiO2/Fe3O4 coated with TiO2 (Magnox) for plausible tertiary wastewater treatment. For this, pilot plant 45 L equipped an Ultraviolet light (UVC) lamp was employed to study the degradation model contaminant, enrofloxacin (ENR), as well water disinfection (elimination Escherichia coli and Clostridium perfringens). The influ...

This study aiming to determine the optimal conditions degrade an organophosphate pesticide diazinon (DZN) at low levels concentrations (μg.mL−1) and identify by-products generated. The degradation processes utilized were Fenton photo-Fenton. iron concentration [Fe2+], hydrogen peroxide [H2O2], solution pH are investigated parameters. Doehlert three-parameter experimental design was applied mode...

In this study, Chemical Oxygen Demand (COD) removal efficiency from wood processing wastewaters by Fenton Process (FP) and Photo Electro (PEFP) were examined. Important operating parameters such as pH, Fe+2 concentration/(amper for PEFP), H2O2 concentration reaction time optimized. Optimum operation conditions of the FP pH 3.5, 1.4 gr/L Fe2+ 50 150 min. while they 3.00, 9.99 mA/cm2 current dens...
