Nanoplastics mineralization by the intensified photo-Fenton process

Global NEST International Conference on Environmental Science & Technology, 2022
The widespread presence of microplastics (MPs) and nanoplastics (NPs) in aquatic systems has become one of the most challenging environmental issues nowadays. Although advanced oxidation processes (AOPs) have been widely studied for the treatment of persistent contaminants in water, their application for MPs and NPs removal have been scarcely addressed.

Toxicity evaluation of the landfill leachate after treatment with photo-Fenton, biological and photo-Fenton followed by biological processes

Journal of Environmental Science and Health, Part A, 2018
The objective of this study was the toxicity evaluation of landfill leachate samples both raw and after treatment by photo-Fenton (PF), biological (Bio) and photo-Fenton followed by biological (PF-Bio) processes. The organisms Artemia salina and Lactuca sativa were exposed to the leachate in different dilution.

Mineralization of Catechol by Fenton and Photo‐Fenton Processes

CLEAN – Soil, Air, Water, 2012
AbstractCatechol is one of the most abundant phenolic components of olive mill wastewaters. In this article, the mineralization of this compound in synthetic aqueous solutions by the Fenton and photo‐Fenton processes is studied. It has been found that for 1.44 mM catechol, the total organic carbon of solutions is reduced about 94.4% at best after 60 ...

Photo-Fenton process for excess sludge disintegration

Process Biochemistry, 2007
For the minimization of excess sludge in activated sludge process, the photo-Fenton reaction was applied as a novel technique and its effectiveness was experimentally examined. A batch study was conducted to elucidate parameters governing the activated sludge integration by the photo-Fenton process such as the concentrations of sludge, Fe ion and ...

Degradation of nitrophenols by Fenton and photo-Fenton processes

Journal of Photochemistry and Photobiology A: Chemistry, 2005
Abstract The degradation of four nitrophenols (NPs), namely 2-nitrophenol (2-NP), 4-nitrophenol (4-NP), 2,4-dinitrophenol (DNP), 2,4,6-trinitrophenol (TNP) with Fenton process, solar- and UV-assisted Fenton processes were investigated and compared for their treatment efficiency. The maximum mineralization observed for mono-NP, DNP and TNP was 32%, 25%

Oxidation of aqueous chlorobiphenyls with photo-fenton process

Chemosphere, 1999
Abstract Research of 4-CBP and 4,4′-CBP in aqueous solution using the photo-Fenton process was conducted in two parts. The first part of the study explored the treatment efficiency, revealing that 4-CBP and 4,4′-CBP were easily adsorbed onto glass.

Petrochemical Wastewater Treatment by Photo-Fenton Process

Water, Air, & Soil Pollution, 2015
In recent decades, the rise in the generation of extremely toxic and refractory wastewaters, as petroleum refinery plant effluents, is demanding increasingly efficient treatment technologies, among which photo-Fenton advanced oxidation processes are highlighted due to their rapid and effective petroleum-derived pollutant degradation.

Mineralization of pentafluorophenol using photo-Fenton processes

Desalination, 2010
Abstract The mineralization of pentafluorophenol (C 6 F 5 OH) in water using UV-C light and Fe(II) sulfate/Fe(III) oxalate with H 2 O 2 was examined to develop a technique to counteract persistent and bioaccumulative C 6 F 5 OH to harmless species. Photo-Fenton process led to efficient degradation of C 6 F 5 OH to fluoride ions and CO 2 .

Oxidation of aqueous chlorophenols with photo-Fenton process

Journal of Environmental Science and Health, Part B, 1998
Abstract Research of 2,4‐chlorophenol and 2,4,6‐trichlorophenol in aqueous solution using the photo‐Fenton process was conducted in two parts. The first part of the study explored the treatment efficiency and reaction rate expression of 2,4‐chlorophenol and 2,4,6‐trichlorophenol. With respect to the simulated experimental data, the relationship between

Degradation of polyolefins by Fenton and Photo- Fenton processes

2021
Due to its great characteristics and low price, the production of plastic materials has increased significantly in the last few decades. Unfortunately, most plastic waste is not disposed of appropriately what consequently caused their entering in the environment.
