The invention belongs to the technical field of medicine detection, and discloses a method for rapidly and quantitatively detecting the adsorption capacity of medicinal carbon or activated carbon. The method comprises the following steps: (1) preparing an antipyrine aqueous solution with the concentration of 5.0-15.0 mg/ml; (2) adding an antipyrine aqueous solution into a medicinal carbon or activated carbon sample to be detected, controlling the weight ratio of the sample to antipyrine to be 1.5-2.5, shaking for more than 30 minutes, and filtering to obtain a test solution; and (3) measuring the amount of residual antipyrine in the test solution by adopting an ultraviolet spectrophotometric method, and calculating the adsorption capacity of the medicinal carbon. According to the present invention, the adsorption capacity of the medicinal carbon on antipyrine is rapidly and quantitatively detected based on the ultraviolet spectrophotometer, the adsorption capacity of the medicinal carbon on toxic molecules ca
