The invention provides a ferrite adsorbing material used for adsorbing rare earth elements. The ferrite adsorbing material is formed by a ferroferric oxide, and the crystalline phase of the ferrite adsorbing material is an inverse spinel structure; the invention also provides a rare earth element adsorbing method comprising the following steps: a water body containing the rare earth elements is provided, the ferrite adsorbing material is added to the water body to form a mixed solution, the mixed solution is adjusted to alkaline, and therefore the ferrite adsorbing material is enabled to adsorb the rare earth elements.
