Abstract: Provided is an amination method for a polystyrene-type resin, and a method for immobilizing an enzyme using an aminated polystyrene-type resin. The amination method includes: in a solvent, a catalyst is used to catalyze a polystyrene-type resin and an enamine salt to perform a Friedel-Crafts alkylation reaction, to obtain an aminated polystyrene-type resin, herein the catalyst is a Lewis acid catalyst. By means of the Friedel-Crafts alkylation reaction, the enamine salt is grafted onto the polystyrene-type resin, and the polystyrene-type resin is aminated. The conditions of the Friedel-Crafts alkylation reaction are easy to control, the post-treatment process is simple, and it is only necessary to remove the catalyst and the unreacted enamine salt by washing. Therefore, the above amination method in the present application has few steps and is simple and easy to implement. Meanwhile, the amination method further avoids the use of a noble metal catalyst, thereby reducing production cost.
