Photocatalytic degradation of Reactive Red 141 dye by photo-Fenton process

Photocatalytic bleaching using AOPs is a field of interest for the researchers as it offers an interesting approach for colour removal and reduction to simple inorganic compounds. It was found that treatment with Fenton Reagent was also effective for the colour removal and convert into smaller pollutants. Photocatylitical degradation of Reactive Red 141 was studied in detail using H2O2/Fe3+. The experimental results showed that photocatalytic degradation depends on the dye concentration, catalyst concentration, H2O2 concentration, pH and light intensity. Photodegradation optimized for these parameters. This photodegradation follows pseudo first order kinetics. Experimental results shows effectiveness of photocatalytical degradation of RR 141 using Fenton system.
