D**1G Macroporous styrene series weakly alkaline 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, 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.
