电吸附环丙沙星性能的研究

Study on the Performance of electric Adsorption of Ciprofloxacin

本文以多孔活性炭作为电极材料,利用电吸附技术去除废水中的环丙沙星,考察不同初始浓度、操作电压对电吸附性能的影响。多孔活性炭比表面积为1568 m^(2)/g,具备微孔和介孔分级结构,适合用于电吸附电极材料。实验结果表明,初始浓度为60 mg/L,电压为1.4 V,环丙沙星的去除率最佳,达到72.92%。初始浓度过低双电层无法完全利用,浓度过高将导致双电层过饱和,电吸附效果不佳。而操作电压太低,双电层作用较弱,电压太高导致副反应发生,环丙沙星去除率下降。本文利用电吸附技术去除环丙沙星废水,也为抗生素废水的治理提供新思路。

In this paper,porous activated carbon was used as electrode material to remove ciprofloxacin from wastewater by electric adsorption technology.The effects of different initial concentrations and operating voltages on the electric adsorption performance were investigated.The specific surface area of porous activated carbon is 1568 m^(2)/g,with microporous and mesoporous hierarchical structure,which is suitable for electroadsorption.The experimental results showed that when the initial concentration was 60 mg/L and the voltage was 1.4 V,the best removal rate of ciprofloxacin reached 72.92%.The double electric layer cannot be fully utilized with low initial concentration,while the double electric layer will be over saturated with high initial concentration and the electric adsorption effect is poor.The double-layer effect is weak with low operating voltage,while the side reactions occur with high operating voltage.In this paper,the removal of ciprofloxacin wastewater by electric adsorption technology provides a new idea for the treatment of antibiotic wastewater.
