description	The invention discloses modified nano zero-valent iron with a core-shell structure as well as a preparation method and application thereof, belongs to the technical field of heavy metal pollution remediation, and solves the technical problem that the existing nano zero-valent iron cannot completely overcome the defects of the nano zero-valent iron so as to remarkably improve the reduction removal efficiency of heavy metal ions. The invention discloses a preparation method of modified nano zero-valent iron with a core-shell structure, which comprises the following steps: chelating ferrous ions by adopting an amino carboxylic acid compound, adding a KBH4 solution into a mixed solution to form amorphous nano zero-valent iron, and reacting for a certain time to finally obtain the modified nano zero-valent iron with the core-shell structure. According to the method, the modified nanoscale zero-valent iron material with the core-shell structure can be prepared through one step and one modified material, and the pre
