THE EFFECT OF OPERATIONAL PARAMETERS ON DECOLOURISATION OF TEXTILE DYES AND COMPARISON EFFICIENCIES OF THE UV/H2O2, FENTON AND PHOTO-FENTON PROCESSES: A REVIEW

Abstract

The applicability of advanced oxidation processes (AOPs) such as UV/H 2 O 2 , Fenton and photo-Fenton for removal of textile dyes from wastewater and effect of operational parameters (initial dye concentration, initial H 2 O 2 concentration, initial Fe 2+ concentration and initial pH) on these processes have been reviewed. A numerous works have been reported where AOPs were used for degradation of textile dyes and results showed that they are very effective. By comparing the rate of these processes it was found that photo-Fenton process is more efficient than Fenton and UV/H 2 O 2 process.
