Used extensively in ion exchange processes, particularly for the purification and separation of ions in aqueous solutions. It is commonly applied in water treatment to remove contaminants like heavy metals and anions. In biochemical laboratories, it aids in the purification of proteins, nucleic acids, and other biomolecules by facilitating anion exchange chromatography. It is also employed in the pharmaceutical industry for drug purification and in the food industry to decolorize and deionize products such as sugar syrups. Additionally, it plays a role in catalytic applications and in the recovery of valuable metals from industrial waste streams.
