Fundamentos e aplicações ambientais dos processos fenton e foto-fenton
(Sociedade Brasileira de Química, 2007-04-01)
Wastewater and soil treatment processes based on Fenton's reagent have gained great attention in recent years due to its high oxidation power. This review describes the fundaments of the Fenton and photo-Fenton processes ...
Estudo da aplicação do processo foto-Fenton solar na degradação de efluentes de indústria de tintas
(Editora Unesp, 2004-01-01)
Neste trabalho estudou-se a aplicabilidade do processo foto-Fenton utilizando irradiação solar no tratamento de dois efluentes (A e B) de uma indústria de tintas. Foi avaliada a influência da concentração inicial de peróxido ...
Prediction via neural networks of the residual hydrogen peroxide used in photo-fenton processes for effluent treatment
(Wiley-Blackwell, 2007-08-01)
This communication proposes the use of neural networks in the prediction of residual concentrations of hydrogen peroxide from the treatment of effluents through Advanced Oxidative Processes (AOP's), in particular, the ...
Degradation of sulfamethoxazole in water by solar photo-Fenton. Chemical and toxicological evaluation
(Pergamon-Elsevier B.V. Ltd, 2009-09-01)
In this work, the photocatalytic degradation of the antibiotic sulfamethoxazole (SMX) by solar photo-Fenton at pilot plant scale was evaluated in distilled water (DW) and in seawater (SW). Degradation and mineralization ...
Photo-Fenton process for treating biological laboratory wastewater containing formaldehyde
(Editora Unesp, 2010-01-01)
Laboratórios e centros de pesquisa consomem uma grande variedade de substâncias químicas perigosas e, consequentemente, geram resíduos contendo-as, como por exemplo: resíduo de formaldeído. O formol é bastante empregado ...
Sistema de injeção em fluxo espectrofotométrico para monitorar peróxido de hidrogênio em processo de fotodegradação por reação foto-Fenton
(Sociedade Brasileira de Química, 2001-04-01)
A flow injection spectrophotometric system was projected for monitoring hydrogen peroxide during photodegradation of organic contaminants in photo-Fenton processes (Fe2+/H2O2/UV). Sample is injected manually in a carrier ...
Parameters affecting sulfonamide photo-Fenton degradation - Iron complexation and substituent group
(Elsevier B.V. Sa, 2012-03-15)
The photo-Fenton degradation of the sulfonamide antibiotics sulfadiazine (SDZ) and sulfathiazole (STZ) mediated by Fe(III)-oxalate was studied in this work. The influence of iron complexation. H2O2 concentration and pH on ...
Evaluation of the combined solar TiO2/photo-Fenton process using multivariate analysis
(2004-04-21)
The effect of combining the photocatalytic processes using TiO 2 and the photo-Fenton reaction with Fe3+ or ferrioxalate as a source of Fe2+ was investigated in the degradation of 4-chlorophenol (4CP) and dichloroacetic ...
Use of iron and bio-oil wastes to produce highly dispersed Fe/C composites for the photo-Fenton reaction
(Environmental Science and Pollution Research, 2018)
