    Abstract

    This study presents the degrdn. of methyl orange in a synthetic soln. using an electro-oxidn. technique. A novel polymer disk electrode was fabricated in this work using injection molding. Such an electrode is low cost, mass produced, and efficient to achieve a complete decolorization of methyl orange in the synthetic soln. The performance of the electrode was studied comprehensively. The degrdn. of methyl orange was accomplished in only 800 s. at optimum operating conditions of 0.1 M KCl electrolyte soln. and const. applied current of 5 mA. The results revealed that the degrdn. of dye follows an indirect electro oxidn. mechanism. It was also found that stirring is a crucial requirement to improve the mass transfer and to enhance the decolorization rate. The effect of changing the applied current, supporting electrolyte, electrolyte concn., and initial dye concn. were also investigated. [on SciFinder(R)]
