Abstract

A fast and facile approach for decomposition of model organic dyes through high voltage corona dis-charge in solution was presented. A comparative study of the significant potential of this technique fordegradation of 8 different types of standard organic compounds such as Phenol Red (PR), Methyl Orange(MO), Diamine Green B (DGB), Pyrogallol Red (PYR), Bromocresol Green (BCG), Bromochlorophenol Blue(BCB), Naphtol Green B (NGB) and Crystal Violet (CV) has been performed. The decomposition rate of dyesunder corona discharge was evaluated by measuring the changes in absorption peak of model dye at dif-ferent discharge times using ultraviolet–visible absorption spectroscopy (UV–vis). The results revealedthat corona discharge at ambient air significantly enhanced the degradation rate of standard dyes. Inaddition, a possible mechanism for degradation of dye molecules under corona discharge process wasproposed based on our observations. It has been found that this process, which is based on the most effi-cient energetic species, is much more powerful than other conventional methods such as photocatalyticmaterials.
