摘要

采用液相还原法制备乳化纳米零价铁（E-nZVI），并与Mg(OH)2结合形成复合材料（E-nZVI@CM）。XRD， SEM和XPS分析表明，纳米级颗粒的团聚减少，提高了水溶液中U（VI）的去除效率。动力学行为研究表明，E-nZVI@CM的去除机制包括吸附和还原过程，最大去除率为287.36 mg·g−1，表明E-nZVI@CM是处理放射性废水的有效材料。图形抽象

Interfacial OH− ions induce the capture of U(VI) from wastewater by modified nano zero-valent iron

The emulsified nano zero-valent iron (E-nZVI) was synthesized using a liquid reduction method and combined with Mg(OH)₂ to form a composite material (E-nZVI@CM). XRD, SEM, and XPS analyses revealed that the agglomeration of nano-scale particles was reduced, enhancing the removal efficiency of U(VI) from aqueous solutions. The kinetic behavior study indicates that the removal mechanism involves adsorption and reduction processes, The maximum removal capacity of 287.36 mg·g⁻¹, showing that E-nZVI@CM is an effective material for treating radioactive wastewater.
