Immobilized nanoscale zero‐valent iron on natural zeolite (NI‐NZ) was synthesized for remediation of antibiotics‐contaminated wastewater. A series of characterization methods confirmed the success of preventing the agglomeration of nanoscale zero‐valent iron particles, using natural zeolite as supporting media. The equilibrium data fitted well with the Langmuir and Temkin models, whereas the pseudo‐second‐order and Elovich kinetic models were suitable to describe the kinetic data. The versatility of NI‐NZ was also tested in a coagulation‐flocculation process which increased the removal of tetracycline from 10 to 75 %.

纳米零价铁负载天然沸石在四环素去除工艺中的应用

合成了固定在天然沸石（NI NZ）上的纳米级零价铁，用于修复受抗生素污染的废水。一系列表征方法证实了使用天然沸石作为支撑介质，成功防止纳米级零价铁颗粒团聚的成功。平衡数据与Langmuir和Temkin模型非常吻合，而伪二级动力学模型和Elovich动力学模型则适合描述动力学数据。NI-NZ的多功能性也在凝结-絮凝过程中进行了测试，该过程将四环素的去除率从10％提高到75％。
