AMBERLITE™ Ion Exchange Resins and Polymeric Adsorbents

AMBERLITE™ Ion Exchange Resins and Polymeric Adsorbents are available in a very wide range of chemical compositions and polymer structures and have been used for decades in a high-value applications including water treatment in industrial and power generation plants, drinking water, food processing, chemical processing, bioprocessing, and pharmaceutical formulations.


AMBERLITE™ IRC748i Chelating Resin is a macroreticular, iminodiacetic acid chelating cation exchange resin with high selectivity for calcium, magnesium and strontium in chlor-alkali brines. AMBERLITE IRC748i resin also exhibits high selectivity for heavy metal cations over alkali metal ions found in various process and waste streams. Selectivity is achieved by the iminodiacetic acid functionality chemically bound to a macroreticular resin matrix. Because of the high preference of AMBERLITE IRC748i resin for metals and excellent kinetic performance, it can remove most metals from solutions even in the presence of high concentrations of sodium or calcium salts, with very low metal leakage. The macroreticular structure of AMBERLITE IRC748i resin is highly resistant to osmotic shock and has excellent physical stability.
