Electro-Oxidation–Plasma Treatment for Azo Dye Carmoisine (Acid Red 14) in an Aqueous Solution

Treatment of Aqueous Solution Containing Acid red 14 using an Electro Peroxone Process and a Box-Behnken Experimental Design

Background & Aims of the Study: Azo dyes utilized in industrial processes, such as the textile manufacturing, lead to the creation of huge amounts of colored wastewaters that contain non-organic and organic constituents. Therefore, it is necessary to search for remedies in this regard. This study investigated the degradation and mineralization of Acid red 14 (AR14), which is a mono Azo dye gene...

Photocatalytic degradation of an azo dye, Acid Red 27, in aqueous solution using nano ZnO

Photocatalytic degradation of Acid Red 27 by nano ZnO has been investigated under different conditions. Optimum experimental conditions on catalyst amount, pH and dye concentration have been determined. Addition of some inorganic oxidizing species such as H2O2, K2S2O8 and KBrO3 up to a certain concentration increases the rate of degradation. The photodecolourisation and degradation kinetics are...

Photocatalytic Degradation of Azo Dye Acid Red 14 from Aqueous Solutions Using MWCNTs Nanocatalyst

Background & Aims of the Study: Azo Dyes are the most hazardous materials in different industries. Dyes and pigments used in industries for applications such as textiles, leathers, papers, foodstuffs, additives, etc. Application amounts of azo dyes in industries which can cause severe health problems in human and environmental pollutant problems. So, color wastewaters decomposition plan are...

Degradation of azo dye orange G in aqueous solution

Application of Photo-Fenton System (UV/ H2O2/ Fe2+) for Efficient Decolorization of Azo-Dye Acid Yellow 17 in Aqueous Solution

 Herein we report, the robustness of UV/H2O2/Fe2+ system for efficient decolorization of azo-dye Acid Yellow (AY17) solution. It has been found that 88% AY17 decolorized by UV/H2O2/Fe2+ system in 25 minutes under the following optimized conditions; [dye] = 0.14 mM, [H2O2] =1.0 mM, [Fe<s...
