Degradation of Reactive Red 120 dye by a heterogeneous Sono-Fenton process with goethite deposited onto silica and calcite sand

Decolorization and COD Removal of Reactive Yellow 16 by Fenton Oxidation and Comparison of Dye Removal with Photo Fenton and Sono Fenton Process

Wastewaters from textile industry contain various pollutants including a high content of organic matter, surfactants, additives and dyes. Dyes have obtained notoriety as hazardous substances, because most of them are toxic and considered to be resistant to biodegradation. Recently, advanced oxidation processes (AOP) have received considerable attention because it is possible to degrade organic ...

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

Elimination of Reactive Red 120 (RR-120) Dye from Aqueous Solution by the using of Date Cores Particles

toxicity, cancinogenic activity, and mutagenicity. The purpose of this study was evaluation of the removal of Reactive Red 120 (RR-120) dye from aqueous solution by date Palm (Phoenix dactylifera) seed particles. Batch adsorption studies carried out to study various parameters included contact time, initial concentration of Reactive Red 120, pH, and adsorbent dosage. The concentration of dye wa...

Photocatalytic and Sonophotocatalytic Degradation of Reactive Red 120 using Dye Sensitized TiO2 under Visible Light

The accelerated sonophotocatalytic degradation of Reactive Red (RR) 120 dye under visible light using dye sensitized TiO2 activated by ultrasound has been carried out. The effect of sonolysis, photocatalysis and sonophotocatalysis under visible light has been examined to study the influence on the degradation rates by varying the initial substrate concentration, pH and catalyst loading to ascer...

Heterogeneous Fenton Process Using the Mineral Hematite for the Discolouration of a Reactive Dye Solution

This work reports a study on the heterogeneous Fenton reaction using hematite powder (Fe2O3) in suspension for the discolouration of the reactive dye Drimarene Red X-6BN in aqueous solutions. The efficiency of the process was studied as a function of the experimental conditions: initial pH; H2O2 dose; and hematite powder concentration; all of which showed a strong effect on the reaction kinetic...
