The MB molecules were decolorized by the conventional electrochemical technique using Pt electrode in the presence of active supporting electrolytes. At acidic pH around 2 and in the presence of KCl, MB molecules were oxidized both in the positive and negative potential windows in different routes due to chemical degradation followed by electrochemical hypochlorite generation and LMB formation,
respectively. The maximum oxidative degradation rate (at +1.0 V) and electron exchange rate (species, MB+ to LMB at −0.7 V) were ∼78.2 × 10−3 min−1 and ∼8.3 × 107 L mol−1 s−1, respectively. Electrochemical bleaching of aromatic compounds like MB+ can potentially be executed through chemical oxidation processes followed by electrochemical approaches which might be adopted by the effluent treatment plants to degraded textile effluents with high percentage of dye-destruction.
