摘要: This paper described a plasma degradation of Brilliant Green (BG) by glow discharge electrolysis. Various influencing factors such as the voltage, the distance between cathode and anode were examined. Ultraviolet (UV) absorption spectra, gas chromatogram–mass spectrum (GC–MS), and chemical oxygen demand (COD) were used to monitor the degradation process and to identify the major oxidation intermediates. It was confirmed that benzoic acid, 1, 2, 3, 4, 5, 6-cyclohexanehexaol, and carboxylic acids (eg, oxalic acid …
