【 摘 要 】

Abstract Taguchi optimization method (L32 orthogonal array) was applied as an experimental design to determine optimum conditions for methylene blue dye removal from aqueous solutions by electrocoagulation (EC). Various electrocoagualtion parameters such as initial pH, time of electrolysis, concentration of dye, electrodes gap, applied current, solution temperature, amount of supporting electrolyte, design and materials of electrodes were investigated. The results have been analyzed using signal-to-noise (S/N) ratio and analysis of variance (ANOVA). The amount of electrolyte parameter has been found to be the most significant parameter on the color removal. The study shows that the Taguchi’s method is suitable to optimize the experiments for dye removal.
