The invention relates to a modified aluminophosphate molecular sieve filter tip adsorbing material and a preparation method and application thereof, and belongs to the technical field of cigarettes. The adsorbing material belongs to a metal Fe modified APO-5 molecular sieve. The preparation method comprises the following specific preparation steps: preparation of FeAPO-5 initial gel, crystallization, drying, roasting and the like; the prepared adsorbing material is a mesoporous APO-5 molecular sieve with uniform bore diameter, the electronegativity of the adsorbing material is changed and B acid site centers are generated after Fe atoms enter an APO-5 skeleton through crystalline substitution, and after the absorbing material is used for preparing compound filter tips in cigarette filter tips, the release amount of phenol, HCN and crotonaldehyde in cigarette main stream smoke can be effectively reduced, so that the adsorbing material has relatively good popularization and application values.
