Abstract
This invention relates to ion exchange resins that have a reduced amount of physically adsorbed organic compounds, as well as methods of producing and using such resins. In particular, the amount of extractable total organic carbon on the resins may be less than about 200 parts per trillion by wet weight, as measured using gas chromatography/mass spectrometry. This invention also relates to methods of treating water that use such resins.
