This invention discloses a deep defluorination agent and its application method, specifically relating to the field of defluorination agents (GMS-FS series products). It includes a valence-state switching active phase, a reaction interface building component, a dynamic electronic regulation component, and a structure adjustment and protection component. The valence-state switching active phase provides a reversible valence-state transition reaction center, achieving specific capture of fluoride ions through an electron trapping effect when interacting with them. The reaction interface building component forms a polar gradient interface layer on the surface of the defluorination agent, guiding fluoride ions to migrate towards the active center and locally enrich them, thereby improving defluorination efficiency. By constructing a rare metal valence-state switching active phase with La2O3 and UO2 as its core, combined with a polar gradient interface guiding layer and a dynamic electronic regulation mechanism, preferential migration and specific capture of fluoride ions are induced in a multi-ion coexistence environment, achieving stable deep defluorination under high salinity and highly competitive ion conditions.
