Amberlite IR120, Na resin is widely used in water softening processes to remove calcium and magnesium ions, replacing them with sodium ions to prevent scale formation in pipes and appliances. It is also employed in the purification and separation of various chemicals in industrial processes, particularly in the pharmaceutical and food industries, where it helps in demineralizing and deionizing water. Its high ion-exchange capacity and durability make it a reliable choice for applications requiring efficient ion removal and recovery.
