Product Description

D301 Macroporous Styrene Series Weakly Base Anion Exchange Resin

1. Description

This is a kind of anion exchange resin which has tertiary amine groups in

styrene-divinylbenzene copolymer. It can remove effectively organic coloring

matters, inorganic acids and silicates from acidic and nearly neutral medium,

with its weak alkalinity. It also can adsorb the big-sized impurities and be used

in non-aqueous solution. This resin has good properties, such as highly-efficient

regeneration capability, large exchange capacity, strong contamination

resistance, excellent physical strength etc.
