The invention discloses a fiber-supported liquid-liquid extraction method for grease sample detection, which adopts natural fiber or synthetic fiber as an internal filler, and the natural fiber or synthetic fiber has a large specific surface area and can well adsorb grease to be detected and an extraction solvent. The to-be-detected grease and the extraction solvent can be effectively mixed on the surface of the natural fiber to obtain the extraction liquid. The natural fiber or the synthetic fiber is used as the internal filler, and the steps of activating, balancing, cleaning and the like on the sample are not needed, so that the detection process is greatly simplified while the detection precision is ensured. The method provided by the invention is a great innovation in grease sample detection, and has remarkable economic and social benefits. The invention further discloses a fiber-supported liquid-liquid extraction device for detecting the grease sample, the device is simple in structure and convenient to
