Weakly basic styrene anion exchange resin with large pores 
Catalog Number IER-2208
Description Weakly basic styrene anion exchange resin with large pores is an anion exchange resin with a tertiary amine group on a copolymer of styrene and divinylbenzene with a macroporous structure. It has a weak alkalinity and can effectively exchange inorganic acids and silicic acid roots in acidic and nearly neutral media, and can adsorb impurities with large molecular sizes as well as be used in non-aqueous solutions. The resin has the advantages of high regeneration efficiency, large exchange capacity, strong anti-pollution ability and good mechanical strength.
