The present invention discloses a copper-doped iron metal-organic framework, a preparation method thereof, and an application method for activation of persulfate to treat organic wastewater. The copper-doped iron metal-organic framework is prepared by solution impregnation method, using relatively large specific surface area and more hollow structures of the iron metal-organic framework to effectively load copper ion.
