Applying chloride-mediated EO favors textile ,wastewater, treatment, due to the presence of chloride in such ,wastewater, resulting from ,dye, fixation on fibers (Palma-Goyes et al. 2015). The active chlorine species generated during electrochlorination have a great affinity to chromophoric groups, in such a way that a high rate and efficient decolorization of dyes are fulfilled.

Three acid anionic dyes were applied in the adsorption experiment: Acid Blue 40 (an azo-type dye), Acid Orange 56 (a typical anthraquinone dye) and Methylene Blue (a common aromatic dye). For convenience, we defined each dye culture medium like this, for example, B-40(5) represents 5 mg Acid Blue 40 dispersed into 100 mL of Czapek–Dox culture medium.
