The invention discloses imprinted polymer capable of selectively gathering F-ions and a preparation method and application thereof.A La2+-Fe3+-Mg2+-F-- compound is weighed and placed into a small beaker, acetonitrile and dimethyl sulfoxide are added, after shaking, functional monomer vinylpyridine is added, nanometer TiO2 with a modified surface is added, after mixing, a cross-linking agent ethylene glycol dimethacrylate and an initiator azodiisobutyronitrile are added, after intensive mixing, the mixture is transferred to a round-bottom flask, ultrasonic degassing is conducted, argon is inflated, the flask is sealed, a polymerization reaction is conducted for 24 h, the obtained bulk polymer is smashed, sieved, eluted many times, filtered and dried, and then the imprinted polymer is obtained.The obtained composite imprinted material polymer is loose in structure, can efficiently and quickly adsorb F-ions in a high-recognizability mode, and therefore the imprinted polymer can separate and gather F-ions; the im
