Amberlite^® IRA-900 (CAS 9050-97-9)

Amberlite® IRA-900 is an advanced anion exchange resin known for its robust performance in selectively removing and recovering anions from diverse solutions, thanks to its cross-linked acrylic matrix embedded with quaternary ammonium groups. These functional groups facilitate the exchange of anions in the solution for chloride ions originally loaded on the resin. This ion exchange process is driven by the electrostatic interactions between the positively charged quaternary sites and the negatively charged anions, making it highly effective and efficient. Employed extensively in both research and industrial settings, Amberlite® IRA-900 has proven particularly useful in environmental science for the removal of detrimental anions such as nitrates, phosphates, and sulfates from contaminated waters. Additionally, it is utilized in analytical chemistry for the purification and separation of anionic compounds in complex mixtures. Its high capacity, selectivity, and stability under various chemical and thermal conditions also make it valuable for applications including the recovery of precious metals and the recycling of industrial wastes. Amberlite® IRA-900′s versatility and durability thus make it a critical component in developing new materials and processes, particularly in water treatment technology and sustainable chemical processing innovations.
