The method comprises the following specific steps: adding deionized water and the allium macrostemon extract in a certain volume ratio into a three-neck flask at room temperature, mixing for a period of time, and heating after the mixture is uniformly mixed; after the temperature is raised to a certain temperature, adding an iron source and an alkali source to react for a period of time, and waiting for the reaction to be complete; pouring out the product, performing magnetic separation, cleaning the product obtained by the magnetic separation, performing suction filtration, and calcining the product obtained by the suction filtration in a muffle furnace at a certain temperature for a period of time; and after the calcination is finished, taking out the product and grinding to obtain the ferroferric oxide nano particles.)
