EFFECTS OF HIGH ENERGITIC RADIATION ON THE REMOVAL AND DETOXIFICATION OF CATIONIC DYE ASTRAZON BLUE FGRL

Öz

Decolorization and degradation of textile dye wastewater by means of high energitic rays are readly applied, which are affected by some factors influence such as pH, dye concentration, toxicity, COD, BOD5 and absorbed dose. Cationic/basic dye of Astrazon Blue FGRL was treated using ionizing radiation and degree of decolorization in air and O2 saturated and H2O2 condition were discussed. The biodegradability (BOD5/COD) of the dye solutions was enhanced by 1, 3, and 3 kGy absorbed dose for air saturated, O2 saturated and 2.6 mmol L-1 H2O2 solutions, respectively. However, optimum irradiation conditions for complete mineralization and decoloration of Astrazon Blue FGRL solutions were found to be 2 kGy pH 8 for air, 7 kGy pH 5 for O2 saturated, 7 kGy pH 5 for 2.6 mmol L-1 H2O2 solutions, respectively. After irradiaiton at optimum conditions, the biorefractory organic compounds of Astrazon Blue FGRL were converted into smaller and biodegradable compounds by radiation technology.
