A recently developed Pd-based electro-Fenton (E-Fenton) process enables efficient in situ remediation of organic contaminants in groundwater. In the process, H₂O₂, Fe(II), and acidic conditions (~pH 3) are produced in situ to facilitate the decontamination, but the role of ubiquitous natural organic matters (NOM) remain unclear. This study investigated the effect of Aldrich humic acid (HA) on t...

ABSTRACT Although traditional Fenton reaction is known for a long time, it is still a perspective method for removal of pollution from wastewater. Applications of electro-Fenton oxidation are commonly used in wastewater treatment. These methods are classified into groups-electrochemical advanced oxidation processes. Typical catalysts for these technologies are Fe2+ ions. Comparison between two ...

Abstract Abatement of water pollution is being a major concern to be dealt with, as the scarcity for basic needs human beings increasing drastically. As part diminishing pollution, treatment industrial wastewater prior disposal plays paramount role. Due typical characteristics pesticide, intermediate waste also challenging issue. In this study three different sequential methodologies (Methodolo...

The electro-Fenton (EF) process was first proposed in 1996 and, since then, considerable development has been achieved for its application wastewater treatment, especially at lab and pilot scale. After more than 25 years, the high efficiency, versatility environmental compatibility of EF demonstrated. In this review, bibliometrics adopted as a tool that allows quantifying well introducing some ...

1. introductionsynthetic dyes and specially azo dyes are common pollutants found in textile and dyeing industries effluent. azo dyes are the most important class of synthetic dyes and and represent about 70% of all world dyes consumption. textile effluent can cause considerable pollution and rise high health risk factors due to loos of 20% of dyes in process and large scale of dyes used in thes...

In this study, Chemical Oxygen Demand (COD) from a pharmaceutical wastewater (PhW) was reduced by several techniques such as electro-Fenton (EF), photo electro-Fenton (PEF) and activated sludge (AS) processes and the obtained data were compared with each other. The effects of several parameters such as pH, current density, H2O2/Fe2+ molar ratio, volume ratio of ...

This study proposed an integrated valorisation system, by combining adsorption and electro-Fenton processes for fast effective micropollutant remediation of a complex pharmaceutical mixture. The pharmaceuticals venlafaxine, fluoxetine trazodone, commonly detected in the environment (river water sediment), were selected this as target pollutants. Initially, degradation process ternary mixture wa...

This paper reports on the development of hybrid water treatment technologies that take advantage of the attributes of activated carbon adsorption and Fenton oxidation through the development of novel hybrid process schemes: i) a continuous Powdered Activated Carbon (PAC) – Fenton process using a dilute suspension of PAC in a well-mixed reactor vessel connected to a submerged ultrafiltration (UF...
