ZG D890 macroporous highly basic styrene anion exchange resin

1. Introduction

Hydrolite ZG D890 is an anion exchange resin containing a tetravalent ammonium group [-N(CH3 ₎ 3OH _] in a styrene-diethylenebenzene copolymer with a macroporous structure. This product is primarily used to remove nitrates and nitrites from drinking water supplies and has good selectivity for nitrates. It can also be used in the sugar industry, where the highly basic exchange group and macroporous structure facilitate the absorption of pigments and impurities in sugar solutions.
