摘要

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.
