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™ IRN170 Ion Exchange Resin is a stoichiometric equivalent mixture of premium, nuclear-grade, uniform particle size, gel, strong acid cation and strong base anion exchange resins, supplied in the H+/OH- forms. AMBERLITE IRN170 mixed bed resin was originally developed for use in BWR condensate polishers to help achieve the lowest possible sulfate levels in reactor water through a combination of the extraordinary oxidative stability of the cation resin, and a particle size balance between the cation and anion resins, which minimizes the formation of a re-separated cation resin layer on the bottom of the service vessels. The exceptionally high total capacity of AMBERLITE IRN170 resin delivers an important benefit for many other nuclear applications including PWR steam generator blowdown treatment, PWR primary system CVCS resin beds, fuel pool demineralizers, and radioactive waste treatment. Since the nuclear-grade resins from all these applications are generally disposed of as radwaste, high capacity and long resin bed life are critical to minimizing radwaste disposal cost and volume. Longer bed life also brings significant operational benefits such as fewer bed change-outs, less resin handling, and fewer chances for radiation exposure.
