Abstract. Various remediation technologies are being developed for the destruction of groundwater pollutants like ...

In this work, the degradation of 2-chloro-4,6-diamino-1,3,5-triazine in aqueous solutions by photo-Fenton process has been investigated. The preliminary results have shown that the degradation of 2-chloro-4,6-diamino-1,3,5-triazine by photo-Fenton process is more rapid and more effective than Fenton and UV/H2O2 processes. The effects of certain experimental parameters on kinetics and efficiency...

Fenton oxidation technology is the general strategy for the treatment of organic compounds-contained wastewater. However, a considerable amount of ferric sludge was produced during the Fenton process as secondary wastes, which were needed to be further removed from the effluent and treated. In this study, heterogeneous catalysts based on ferrite oxide (Cu-Fe-Ce-O) were synthesized and character...

Fenton and Fenton-like processes, both in homogeneous and heterogeneous phases, have been applied to an aqueous solution containing the dye AR 14 in order to study the mineralization and toxicity of the solutions generated after color elimination. The mineralization of AR 14 occurred slower than the decolorization. The Microtox analysis of the treated solutions showed low toxicity intrinsic to ...

Improper disposal of 1,4-dioxane and the chlorinated organic solvents trichloroethylene (TCE) and tetrachloroethylene (also known as perchloroethylene [PCE]) has resulted in widespread contamination of soil and groundwater. In the present study, a previously designed microbially driven Fenton reaction system was reconfigured to generate hydroxyl (HO˙) radicals for simultaneous transformation of...

There is something intriguing and at the same time fascinating that a simple reaction (of Fe ions with H2O2), which was observed by H.J.H. Fenton over 110 years ago, proves to be very difficult to describe and understand. As yet the nature of the oxidizing species obtained in Fenton reaction is still a subject of deliberation, which may be explained by the fact that it is very common in both ch...

This paper evaluates the treatment of textile dyeing wastewater by using steel scrap as adsorbents and heterogeneous catalysts for Modified Fenton oxidation. The efficiency of the process was explored as a function of the experimental parameters: pH, hydrogen peroxide concentration and Steel scrap content. The composites with high steel scrap content were effective to adsorb colour and COD in t...

Wayne S. Fenton, MD, was an accomplished psychiatric researcher, but his colleagues knew him as an equally talented clinician. This memorial recognizes the personal qualities and professional skills that endeared Wayne Fenton to hundreds of mentally ill persons he treated over the course of his professional career. Among these attributes, deep compassion, sincere respect, and tremendous flexibi...

magnetite (feo.fe2o3) nanoparticles immobilized on silica and modified by treatment apolaccase were used to decolorize the industrial wastewater from basic red 9 (br9 by way of fenton and fenton-like processes. the surface changes to the silica were determined by scanning electron microscopy, fourier transform infrared spectroscopy, x-ray diffraction and energy-dispersive x-ray spectroscopy. th...
