Effect of the electrodic material and pH on the electrooxidation of the synthetic tannery wastewater in 0.10 mol L−1 Na2SO4 at 25 mA cm−2: (a) (phenols)/(phenols)0, (b) COD/COD0, and (c) TOC/TOC0 as a function of electrolysis time. Electrolysis conditions: (◊) Ti/SnO2–Sb–Ir and pH 2.4, (◂) Ti/SnO2–Sb and pH 2.4, (■) Si/BDD and pH 2.4, (●) Si/BDD and pH 7.3, and (∆) Si/BDD and pH 12.0 [54].
