%X Glow discharge electrolysis degradation of Eosin B solutions has been investigated. Ultraviolet (UV) absorption spectra, fluorescence spectra (FS), pH meter and atomic force microscopy (AFM) are used to monitor the degradation process. A simple degradation mechanism for Eosin B is proposed on the basis of UV, FS, pH and AFM. It has been found that Eosin B is completely mineralized into CO_ 2 , H_ 2 O and inorganic compound. Within 110 min, the decolorization rate at 513 nm is 95%. The values of pH in the solution are decreased during the degradation process due to the carboxylic acids formed. The reaction constant k is calculated to be 0.0206 min~ -1 by absorbency values, and the reaction may follow well first order kinetics.
