Measurement of Decoloration due to Electron Beam (EB) Irradiation on the Reactive Dyes

EB irradiation is used for treatment of different wastewater including textile effluent and the decoloration effect may be evaluated by several methods. In this work, the effect of EB irradiation on reactive dyes is investigated due to Integrated Absorbance Units (IAU) and the method developed by members of the American Dye Manufacturers Institute (ADMI). The value of pH will affect ADMI measurement at low values but its effect on high values of ADMI and decoloration due to EB irradiation is negligible. According to the results, decoloration due to EB irradiation can be reported based on the ADMI with pH adjustment, ADMI without pH adjustment and IAU data.
