Ionizing Radiation Degradation Study of Disperse Blue 79

Ding, Xiao-Jun, et al. Nuclear Science and Techniques, 2020, 31(2), 21.

Disperse blue 79 is an azo dye that was irradiated by gamma rays or electron beam (EB) as a model dye in this work to study the effect of radiation on the molecular structure. The results showed that pure commercial disperse blue 79 in aqueous solution underwent structural changes when irradiated by gamma rays and EB, but remained stable in powder form.
Gamma ray or EB irradiation experiments
· In the Gamma ray irradiation experiments, disperse blue 79 powder was dissolved in deionized water at a concentration of 10 g/L and irradiated under a ⁶⁰Co gamma-ray source for 17 hours with absorbed doses of 10, 50, or 150 kGy. The irradiated solutions were then dried in a vacuum oven at 60°C. Powder irradiation was conducted by placing 1 g of the dye powder in a polythene bag under the gamma-ray source.
· For the EB irradiation experiments, the disperse blue 79 powder was also dissolved in deionized water at a concentration of 10 g/L and irradiated using a 1.2 MeV electron accelerator with absorbed doses of 10, 50, or 150 kGy. The solutions were then dried in a vacuum oven at 60°C. Powder irradiation was carried out by placing 1 g of the dye powder in a polythene bag directly under the EB source.

Degradation of Disperse Blue 79 Dye in Aqueous Solution via Fenton Process

Hamed, Hussein H., et al. Sci. Int. 2018, 30, 605-611.

This work investigates the color removal and chemical oxygen demand (COD) efficiency of Disperse Blue 79 dye (DB 79) in aqueous solution by Fenton process. The effects of different operating parameters such as Fenton reagent (H2O2, Fe2+) dosage, (H2O2/Fe2+) molar ratio, mixing speed and reaction time on color and chemistry were investigated. The results showed that 85% color removal and 75% COD removal were achieved under the optimum process conditions (33.53 molar ratio (150 mg/L H2O, 20 mg/L Fe), 50 rpm mixing speed and 60 min reaction time).
Degradation of Disperse Blue 79 by Fenton process
· The Fenton method was conducted using a Jar test apparatus, comprising four cylindrical glass beakers with a capacity of 2000 mL each, equipped with a mechanical stirrer with an operational speed ranging from 0 to 200 rpm.
· Initially, 80 ml of the sample dye solution was poured into each beaker, followed by the addition of tap water and Fenton's reagent (consisting of ferrous ions, Fe2+, and hydrogen peroxide, H2O2 30%) to bring the final solution volume to 2000 mL.
