Physical and Chemical Properties | D301 weakly basic anion exchange resin is an ion exchange resin with tertiary amine group [-N(CH3)2] on the macroporous styrene divinylbenzene copolymer. It is weakly alkaline and can be in acidic and near-neutral media. Effectively exchange inorganic acids and silicates, and can adsorb impurities with larger molecular size and use in non-aqueous solutions, the resin has the advantages of high regeneration efficiency, low alkali water consumption, large exchange capacity, strong resistance to organic pollution and oxidation resistance, and good mechanical strength. |
Use | The preparation of pure water and high-purity water is especially suitable for the treatment of water sources with high salt content and organic matter content. |
