Nitrate selective ion-exchange resin PA202

Applications

The macroporous matrix and special ion exchange group functionality imparts ideal nitrate selectivity to Pure PA202 making this resin particularly suitable for nitrate removal even when moderate to high concentrations of sulphate are present.
