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™ IRN317 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 7Li+/OH- forms. AMBERLITE IRN317 mixed bed resin is specifically designed for enhanced performance and long resin life in the Chemical and Volume Control System (CVCS) of Pressurized Water Reactors (PWR). The highly crosslinked matrix of the cation resin delivers the highest total capacity and the best chemical and oxidative stability of any available nuclear-grade resin; the enhanced oxidative stability significantly lowers the release of organic sulfonates, thus reducing sulfate levels in the reactor coolant. The anion resin is regenerated to the OH-form to ensure that less than 0.1% of exchange sites are present in the chloride form or the sulfate form; therefore, AMBERLITE IRN317 resin can effectively control chloride and sulfate impurities even while operating at high background concentrations of lithium and borate.
