ADSORPTION PERFORMANCE OF TC AND Cu2+ BY METAL-ORGANIC SKELETON HYBRID FOAMS

  • 摘要: 针对医药废水中抗生素和重金属难以被有效去除的问题,采用金属有机骨架杂化泡沫MIL-100(Fe)/CMC吸附四环素(tetracycline, TC)和铜离子(Cu2+),利用X射线衍射、扫描电镜、氮气吸附脱附和热重分析技术,分析MOFs杂化泡沫理化性能,通过吸附试验研究杂化泡沫吸附性能影响因素、稳定性和吸附机理。结果表明:MIL-100(Fe)/CMC具有丰富的孔道结构和较高的热稳定性,在初始浓度为30 mg/L,MIL-100(Fe)/CMC投加量为40 mg,吸附时间为16 h,pH=6时,MIL-100(Fe)/CMC对TC和Cu2+的最大吸附容量分别为80.40,80.04 mg/g,且离子强度(NaCl)与吸附性能呈负相关。MIL-100(Fe)/CMC具有良好的吸附和循环再生性能,6次循环再生后对TC和Cu2+去除率均保持在70%以上;MIL-100(Fe)/CMC对TC与Cu2+的吸附为自发放热过程,符合Langmuir等温线模型和拟一级动力学模型。金属有机骨架杂化泡沫对于抗生素和重金属混合污染物去除效果表明其在处理医药废水方面具有广阔的应用前景。
