D301 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, 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.
This product is analogous to :Amberlite IRA-93
