A method of manufacturing absorbent material from bird feather includes the steps of selecting an appropriate feather material, perform a pre-treatment for cleaning and sterilizing the feather material, crushing the feather material into a crushed material of a size of 0.1 um˜1 cm, and performing a modification treatment of the crushed material by surface activation to produce an absorbent material. After the crushed feather material is processed by a modification treatment, the material may be used to manufacture an absorbent material having both deodoring and filtering functions for adsorbing metal ions, organic solvents, grease or volatile gases.
