A macroporous cation exchange resin and its preparation and application method are disclosed. The method involves dispersing polystyrene-divinylbenzene microspheres in dichloroethane to obtain a microsphere suspension. A sulfonating agent, a mixture of fuming sulfuric acid and chlorosulfonic acid, is then slowly added dropwise under cooling and stirring conditions.
