A series of resins was synthesized and analyzed for selective ion-exchange nature for some metals. Substituted aniline was reacted with formaldehyde, melamine. For the synthesis of ion-exchange resins, sulfuric acid was used as a catalyst. These resins were characterized by elemental analysis and studied antimicrobial activities. Synthesized Resin shows ion exchange capability and moderate activity against microbial. Ion exchange resin also showed reusability and stability at an elevated temperature.
