Abstract:
The electrochemical oxidation of anthraquinone dye alizarin red S in simulated wastewater was investigated. In this method, sulfuric acid-modified activated clay was used as catalyst,the graphite plate and titanium net were used as anode and cathode respectively. The effects of initial pH, applied voltage, electrolyte type, ventilation, and the initial dye concentration on decolorization of alizarin red S were studied. From the results, it can be found that decolorizing rate could reach up to 97.1% in 50 min.In case of the initial pH at 3, concentration of 200 mg/L, 3 g/L of sodium chloride, cell voltage at 10 V, 20 g/L catalyst, ventilation at 100 L/h.
