摘要
采用沉淀后高温高压水热法成功合成钴掺杂铁基骨架材料MIL-101(Fe)@Co催化剂,非均相催化活化硫酸盐氧化降解左氧氟沙星模拟废水。研究结果表明:MIL-101(Fe)@Co可有效地活化过硫酸盐氧化降解左氧氟沙星,在底物初始浓度为20mg/L,催化剂投加量为0.4g/L,氧化剂投加量2.0g/L,pH=7.2的实验条件下,左氧氟沙星的去除率达到84%。多次连续的循环实验表明Co掺杂铁基骨架材料MIL-101(Fe)@Co催化剂具有较好的重复利用性,有良好的应用前景。
Co-doped iron-based framework material of MIL-101(Fe)@Co was synthesized by hydrothermal co-precipitation method.MIL-101(Fe)@Co was used as heterogeneous catalyst to catalyze persulfate(PDS)for the degradation of levofloxacin.The experiment results show that the system of MIL-101(Fe)@Co/PDS can efficiently remove levofloxacin.Under the experimental conditions of levofloxacin concentration 20mg/L,PDS dosage 2.0g/L,MIL-101(Fe)@Co dosage 0.4 g/L,solution pH 7.2,the removal rate of levofloxacin reached 84%.The regeneration experiment proves that Co-doped iron-based framework material of MIL-101(Fe)@Co can be used repeatedly and has favorable stability and has good application prospects.
