Study on Photoelectric Decolorization of Auramine O

摘要: 以掺杂氟的SnO₂透明导电玻璃（FTO导电玻璃）为阳极，通过单因素和响应面法优化了碱性嫩黄O的光电降解工艺. 探讨了TiO₂、NaCl质量浓度、环境酸度、降解电压与施加时间等因素对脱色率的影响，并利用响应面法优化了脱色条件. 结果表明：在TiO₂质量浓度为0.13 g/L、NaCl质量浓度为0.43 g/L、环境初始酸度为8.0，施加14.0 V的降解电压30 min后，碱性嫩黄O脱色率可达95.91%.

Abstract: The photoelectric degradation of Aauramine O was optimized by the single factor and response surface method using a fluorine-doped SnO₂ transparent conductive glass (FTO conductive glass) as the anode. The effects of mass concentration of TiO₂ and NaCl, acidity of environment, voltage of electrolysis and time applied on the decolorization rate were discussed, and the decolorization conditions were optimized using a response surface method. The results showed that the decolorization rate of Auramine O could reach 95.91% when the mass concentration of TiO₂ was 0.13 g/L, the mass concentration of NaCl was 0.43 g/L, the initial acidity of the environment was 8.0, and the voltage of electrolysis was 14.0 V for 30 min.
