The Radiation-induced Decoloration of Azo Dye in Aqueous Solutions

Decomposition of a Di Azo Dye in aqueous solutions by

This study examined the photolytic degradation of C.I. Acid Red 73 AR73 diazo dye, in aqueous solution by combined UV, hydrogen peroxide and KMnO4. A continuous circulated photoreactor equipped with a low pressure mercury lamp 15 W, emission 253.7 nm was used. In the first step, potassium permanganate was used for decolourisation of AR73 dye solution. The effect of the key operating variables s...

Oxidation of commercial reactive azo dye aqueous solutions by the photo-Fenton and Fenton-like processes

This paper evaluates the degradation of two azo reactive dyes, C.I. Reactive Yellow 84 (RY84) and C.I. Reactive Red 120 (RR120) by photo-Fenton and Fenton-like oxidation. All experiments were performed on a laboratory scale set-up. The effects of different reaction parameters such as initial pH, contact time, effect of light and hydrogen peroxide concentrations on the oxidation of the dye aqueo...
