Ion Exchange (India) Ltd has recently developed and commercialised several new polymeric adsorbents which find application in the pharmaceutical industry.

Working on the Vander Waats forces principle, polymeric adsorbents INDION PA 500 & INDION PA 800 are capable of removing non-polar substances from polar streams. They are extremely effective in replacing activated carbon, and thus successfully address the carbon disposal issues, which is a serious issue facing the industry nowadays. Moreover, the surface of the adsorbents can be reactivated for repeated use, offering a distinct cost and environmental benefit.

These polymeric adsorbents have been well received by the pharma industry as well as the biotech and process industries for applications of removal of non-polar impurities from fermentation broth, removal of polyphenol and chlorophyll from herbal extracts and removal of phenol from hydrochloric acid.
