In this study, the Fenton process was used to investigate the color removal efficiency of Acid Red 52 and Basic Red 18 dye solutions by direct chemical oxidation. Color and chemical oxygen demand (COD) was successfully removed more than 99% and up to 92% respectively. This article would provide an easy assessment of the viability of using Fenton reagent in acidic conditions, so it is a prom...

19 In this study, we attempt for the first time to couple sonication and photo-Fenton for bacterial 20 inactivation of secondary treated effluent. Synthetic wastewater was subjected to sequential high21 frequency/low power sonication, followed by mild photo-Fenton treatment, under a solar simulator. It 22 was followed by the assessment of the contribution of each component of the process (Fento...

Solar assisted Photo Fenton was compared with advanced oxidation processes for their color and COD removal efficiency and cost effectiveness. H2O2 alone appeared to be inefficient to reduce color and COD content of any effluent. The performance of Fenton process was slightly better, color and COD removals were 45 % and 63% respectively. Photo Fenton treatment of blue effluent resulted into colo...

A simple and sensitive electrochemical biosensor was used to detect tyrosine oxidation induced by hydroxyl radicals generated by Fenton reaction (Fe(2+)/H(2)O(2)). Poly(glu, tyr) (4:1) peptides were immobilized on indium tin oxide (ITO) electrode surface via layer-by-layer assembly technique, and Os(bpy)(3)(2+)-mediated tyrosine oxidation current was employed as the signal reporter of the biose...

Cosmetic industry wastewater is high strength wastewater and it can be difficult to decompose with biological treatment due to its high stability or toxicity. The use of Fenton reagent as a Chemical pretreatment was investigated with a Factorial Experiment where the concentrations of ferrous sulfate, hydrogen peroxide and reaction duration was the main parameters examined for COD and TOC reduct...

The present study aimed to assess and compare the ability to remediate synthetic textile and industrial wastewaters by Fenton treatment, a biological system and sequential treatments using Aspergillus niger (A. niger). All studied treatments were found to be effective in decolorization of the effluents under study. Fenton treatment followed by A. niger showed excellent potential for the maximum...

Decolorization of sunset yellow dye (SY) in an aqueous solution was investigated by Fenton reaction using H2O2/Fe 2+ system. Different parameters controlling the degradation efficiency as pH and H2O2 and Fe 2+ concentrations were evaluated. The optimal operational conditions were found to be [Fe] = 2.55x10 mmol, [H2O2] = 0.2425 mmol at pH 2.7. The study of the Kinetics of decolorization indicat...

I agreewith Fenton and Fenton that the current evidence on the paleo diet might be considered early or preliminary and that further research is critically needed. There is a risk of great societal harm if dietary guidelines and recommendations are issued without a strong foundation of evidence from methodologically robust randomized controlled trials (RCTs), ideally trials comparing different d...
