Abstract: The invention discloses a preparation method of a phenylethanolamine A molecularly-imprinted material, which is characterized by comprising the following steps of: (1) activating silica gel; (2) carrying out double-bond bonding on the silica gel; (3) carrying out chemical grafting on the surface of the silica gel and obtaining grafting particles; and (4) preparing the product: adding the grafting particles into 300-500mg/L phenylethanolamine A aqueous solution, adjusting the pH value of the system to be alkaline, adding a crosslinking agent and heating for reaction; after the reaction is finished, washing off template molecule phenylethanolamine A, drying and obtaining the phenylethanolamine A surface molecularly-imprinted material. Compared with the prior art, the preparation method has the advantages that the preparation process is simple, the operability is strong, and the preparation cost is low; and the molecularly-imprinted material is good in specificity, short in adsorption equilibrium time of phenylethanolamine A, short in elution time and good in elution effect.
