All chemicals used were of AR grade and solutions were prepared using Double distilled Water. Systems containing different concentrations of Indigo Carmine dye were prepared and exposed to different doses of gamma radiations. Decolorization of dye solutions was followed as a function of absorbance. The effect of pH on extent of dye decolorization was studied at three different pH values viz. 3,the actual pH of solution and at 10. Abstract In the present study, the decolorization of aqueous solutions of Indigo Carmine dye which is primarily used as pH indicator and also in the manufacturing of capsules, in surgery used to highlight the urinary tract, was investigated using 60Co as gamma radiation source at a dose rate of 0.386 kGy/hr. The effect of various operational parameters such as initial dye concentration, gamma radiation dose and pH of dye solution on the rate and extent of decolorization was also investigated.
