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™ IRN77

AMBERLITE™ IRN77 Ion Exchange Resin is a nuclear-grade, uniform particle size, gel, strong acid cation exchange resin, supplied fully converted to the H-form. It is processed to the highest purity standards required for treating water in the nuclear power industry. AMBERLITE IRN77 resin contains a minimum of 99% of its exchange sites in the hydrogen form. The uniform particle size and the absence of fine resin beads results in a lower pressure drop compared to conventional resins. The manufacturing process for this resin is controlled to keep inorganic impurities at the lowest possible level. Special treatment procedures are also used to remove traces of soluble organic compounds. These high standards of resin purity will help keep nuclear systems free of contaminants and deposits, and help prevent increases in radioactivity levels due to activation of impurities in the reactor core. AMBERLITE IRN 77 resin has been proven to be highly effective in the primary water treatment to remove fission products, activated corrosion products, and suspended matter; to control the pH of the reactor coolant stream by removing the excess Li-7; for radwaste treatment to remove radioactive cations such as Cs-137 from waste streams; and to remove of cationic radioactive material from spent decontaminating solutions.
