Abstract
In this study, degradation and decoloration of reactive and acid commercial dyes (C.I. Reactive Black 5 and C.I. Acid Red 151) in water under the irradiation with electron beams were investigated. Both dyes in aqueous solutions with the concentration of 100 ppm were irradiated at different doses of 1, 3, 6 and 9 kGy. The changes of the absorption spectra, degree of decoloration, pH, and chemical oxygen demand (COD) were analyzed. In addition to the influence of the absorbed dose the hydrogen peroxide additions on RB5 dye are discussed. The experimental results show that the reactive and acid dyes in aqueous solutions can be effectively degradiated by irradiation with the electron beam. The absorption bands for RB5 and AR151 decreased rapidly at 1kGy irradiation dose and disappeared almost completely at 9kGy. Also the degree of decoloration of RB5 solution at 1kGy dose and with the concentrations of H2O2 up to 5mmol/L was higher than 99.78%. Due to the production of organic and inorganic acidic anions the pH decreased during the irradiation.
