The invention belongs to the technical field of tobacco and particularly discloses a method for measuring the acrylic acid content of a polypropylene tow adhesive for tobacco. The method comprises the following steps of: extracting acrylic acid in a polypropylene tow adhesive sample for the tobacco with water; separating to obtain the solution of polypropylene tow adhesive sample; and quantificationally measuring the acrylic acid content of the solution of polypropylene tow adhesive sample by using a high performance liquid chromatograph and an ultraviolet detector by an external standard method, wherein chromatographic conditions are that: a chromatographic column is a C18 reversed-phase chromatographic column; 0.1 volume percent aqueous solution of phosphoric acid-acetonitrile is taken as a mobile phase and the volume ratio of the aqueous solution of phosphoric acid to the acetonitrile is 85:15-95:5; an elution mode is isocratic elution; the column temperature is between 20 and 40 DEG C; the flow rate is between 0.8 and 1.2 ml/min; the sample size is between 10 and 20 mu l; and a detection wavelength is between 200.0 and 210.0 nanometers. The method of the invention is easy and convenient to operate and has high accuracy, sensitivity, precision and repeatability.
