采用碱性品红溶液模拟印染废水，利用电耦合过硫酸盐法对其进行降解，考察过硫酸盐浓度、电解电流强度、Fe2＋浓度、pH值等因素对碱性品红降解的影响.实验结果表明：当硫酸亚铁初始浓度为40 mg/L，过硫酸钠初始浓度为30 mg/L，pH值为2.0，电流密度为5.00 mA/cm2时，碱性品红的脱色效果最好，脱色率高达90％.本研究还考察了加入不同浓度对苯二酚对碱性品红电耦合降解的影响，当对苯二酚浓度小于为200 mg/L时，随着其浓度的增加，品红脱色效果下降明显.但其反应仍遵循一级动力学规律.

In this study,electro-peraxysulphate process was selected to treat fuchsine solution which is used for simulating dyeing wastewater. Meanwhile we investigated the factors impacts on the fuchsine degradation,such as the concentration of the peroxysulphate,the electric current,the concentration of Fe2+ and the pH. The optimal conditions of fuchsine degradation were obtained in this study. The fuchsine solution decolorization rate could up to 90% when the initial concentration of the ferrous sulfate maintained 40 mg/L,the initial concentration of the sodium persulfate maintained 30 mg/L,the pH kept 2. 00 and the electric current density stabilized at 5. 00 mA/cm2 . This study also investigated the impact of the different concentrations of hydroquinone on the fuchsine degradation reaction. The decolorization rate decreased to 75% when the concentration of hydroquinone reaching 200 mg/L. The reaction kinetics mechanism was also been studied and the results showed the reaction follows the first-order kinetics law with or without hydroquinone exiting.
