The Ti/SnO2-Sb2O3 and Ti/SnO2-Sb2O3/PbO2-Fe electrodes were prepared by thermal decomposition method. Using these two electrodes as anodes, two electro-catalytic oxidation processes were introduced to treat three simulant dye wastewaters, which respectively prepared by the dyes of acid orange II, alizarin red and methylene blue thrihydrate. The results show that these dyes with 100mg/L concentration were degraded by the optimal electrodes. When the current density was 75mA/cm2, the electrolyte concentration was 12g Na2SO4/L, and the degradation time was over 60 minutes, the removal ratio of acid orange II was around 80%, alizarin red was above 65%, and methylene blue thrihydrate was just 45% or so. The results that the removal rates of different dyes were different were explained based on the dyes chemistry structure. It was obtained that the chromophoric group of dye is more complex, the degradation process is more difficult.

Acid Orange Ii

In this paper, the adsorption and decolorization capability of expanded graphite (EG) on the simulated wastewater containing Acid Orange Ⅱwere studied. The experimental results show that the initial concentration of wastewater, the dosage of EG, the pH value and the temperature all have greater effects on the decolorization ratio of simulated Acid Orange Ⅱ wastewater. The dye- wastewater containing lower concentration(＜150 mg/L) of Acid Orange Ⅱ is more suitable to be treated by EG, and approximately 100 mg/L is the preferable concentration. The decolorization ratio increases with the increment of the dosage of EG and the temperature level, but the growth rate obviously decreases at the higher initial concentration. All the decolorization ratios under strong acidic (pH<5) and alkalic (pH>11) conditions are higher than that at the range of 5-11 pH values, the highest value even reaches over 94%, while the decolorization ratio under the latter conditions are only between 75% and 85%.
