Wastewater discharged by textile industries contains harmful stubborn dyes at high concentration. The majority of dyes used in the textile industries are non-degradable; therefore, efficacious treatment of these colors can not be accomplished by customary processes. Radiation treatment has been viewed as a promising procedure for the treatment of industrial waste effluents. In this research, the synergistic effect of gamma radiation on the degradation of reactive black B (BB) dye has been discussed as a function of radiation dose. A UV-VIS spectrophotometer was used for spectrophotometric analysis of sample solutions. Cs137 gamma radiation source was used to irradiate the sample solutions within 0.2-100 kGy dose range. The experimental results showed the effective degradation of BB dye upon irradiation as the absorbance of the sample soltuions was decreased from 1.9 to 0.08; while %decoloration (%Ð) was increased from 23 to 97% within the selected gamma dose range.
