The present work is focused on the homogenous and heterogeneous photo catalytic degradation of acid dye orange 8 a non biodegradable dye from dye manufacturing industries. Dye is treated with Fenton reagent and titanium oxide. Results indicate that dye degradation is dependent on concentration of dye,photocatalyst,and Ph of experiment solutions. Results indicate that dye gradation is more efficient by Fenton reagent rather then titanium oxide

Now a days due to increasing industries the addition of industrial wastes are added to environment which are dangerous for environment. Textile effluents consists of number of dyes, natural impurities and other pollutants. These the environmental concern of these carcinogenic pollutants in contaminated water has drawn the attention of many research workers. Advanced oxidative process are employ using Fenton reagent and titanium oxide

Basic concern is degradation of dye which is carcinogenic and had bad effects on environment.Basically by doing this experiment we get rid of dangerous chemicals which are present in industrial waste water.

COMPARATIVE STUDY OF PHOTODEGRADATION OF DYE ACID ORANGE BY Fenton Reagent AND Titanium Oxide

Rachita Mehta and Menka Susana Mewar university Rajasthan.

The experiment reveal that as more hydrogen peroxide concentration is increased, more hydroxyl radicals produced and more easily of dye degradation occur. the homogeneous photo catalysis is more efficient way for degradation of dyes in industrial waste water which is dangerous for our environment.

Advanced oxidative process have provided advanced catalyzed

oxidation of dye.AOPs based on generation of hydroxyl radicals

which readily converts the organic contaminates into

CO2,H2O.Generally Fenton reagent is used in this experiment. First reaction mixture is irradiated

with photons. the progress of reaction is measured by

spectrophotometer. The rate of decrease of absorbance with time

is monitored by spectrophotometer.simlarly by

using titanium oxide firstly catalyst is added to reaction

mixture then irradiated with visible light. rate of decrease of color with

time continuously monitored
