Photo-degradation of monoazo dye blue 13 using advanced oxidation process (original) (raw)

The high energy radiation overcome the bonding of solute in a solution and H 2 O 2 acts as an oxidizing agent and generates a free radical in the solution which results in photo-degradation by converting the solute in to simple form and resultantly, colored substance under the effect of photo-degradation becomes colorless. The photo-degradation of monoazo dye Blue 13 in an aqueous solution was investigated using a laboratory scale UV lamp in the presence of H 2 O 2 and for maximum degradation of dye, the independent parameter UV power, UV exposure time, pH and H 2 O 2 concentration were optimized. It was found that neither UV in the presence of H 2 O 2 is able to degrade Blue 13 under optimum condition. The results revealed that the use of both UV and H 2 O 2 have pronounced effect on the discoloration of dyes which could be used for management of textile effluents contain waste dyes.
