Degradation of Azo Dye Reactive Black 5 and Acid Orange 7 by Fenton-Like Mechanism

Diesel Degradation in Soil by Fenton Process

Este trabalho descreve a utilização do processo Fenton para degradação de diesel em solo e destaca aspectos comuns em situações reais de contaminação que podem afetar a eficiência da remediação. Foi observado que a maior parte dos hidrocarbonetos presentes no diesel com menos de 14 carbonos foi perdida por volatilização antes da remediação. Em solo franco, cerca de 80% do diesel foi degradado e...

Efficiency of Photo-Fenton Process in Degradation of 2-Chlorophenol

Background & Aims of the Study: Phenolic compounds have been extensively used in industries for applications such as petrochemical, oil refineries, papers, plastics, steel, pharmaceuticals, textiles, coal conversion, and so on. Specified amounts of Phenolic compounds are lost in the process of their manufacturing and utilization and often cause environmental pollution problems....

Evaluating the Efficiency of the Fenton-Ultrasonic Process in Degradation of Trihalomethanes Precursors from Aqueous Environments Using Zero Iron by Response Surface Method

Background: The reaction of natural organic matters (NOMs) with chlorine in the conventional disinfection process results in disinfection by-products (DBP) such as trihalomethanes and haloacetic acids. Due to the potential health risks of trihalomethanes for public health, it has attracted a lot of attention. The purpose of this study is to investigate the performance of combined Fenton-ultraso...

Degradation of Acid orange 3 in aqueous solution by combination of Fly ash/H2O2 and ultrasound irradiation

An efficient and convenient method for degradation of Acid orange 3 (AO3) dye from aqueous solution by combination of Fly ash/H2O2 and ultrasound irradiation is reported. The effects of the relevant operating conditions (pH value, dye concentration, H2O2 concentration, dosage of Fly ash and different reaction system) on the degradation of AO3 were also observed. The combination method was found...
