Radiation Degradation of Reactive Dyes in Aqueous Solution

摘要：

Electron beam and g-rays irradiation were performed to gain the insight of the decoloration and decomposition of reactive dyes in aqueous solution. Decomposition and mineralization of the dyes were investigated with the changes of absorption spectra, degradation efficiency, COD removal, TOC removal and pH changes of the solutions in different irradiation systems. Complete degradation of the dyes was observed at different absorbed doses under diverse irradiation condition. The degradation efficiency was enhanced in the presence of H2O2. The experimental results showed that reactive dyes in aqueous solutions could be removed effectively by electron beam or g-rays irradiation.
