Industrial D201 Anion Exchange Resin – Heavy Metal Recovery & Rare Metal Extraction

This product exhibits performance comparable to the 201 × 7 Strongly Basic Styrene Type I Anion Exchange Resin, demonstrating strong basicity. However, due to its macroporous structure, it possesses superior physical and chemical stability, with high resistance to permeation stress, abrasion, and contamination. It can exchange and adsorb larger ions and molecules. This product can be used in non-aqueous media and is commonly employed as a solid strong base catalyst.

Removal of organic acids and colorants in biochemical mother liquor
D201 macroporous Type I strong base anion exchange resin adsorbs refractory organic acids, chromogenic substances and residual anionic impurities from biochemical mother liquor and extract liquid. Its open pore structure lessens organic fouling risk compared with gel resin. It clarifies feed liquid, reduces COD and improves the recovery rate of target biochemical products during separation.
Chloride and sulfate removal for electrodialysis pre-treatment
Used as pre-treatment resin before electrodialysis and membrane systems, D201 selectively removes chloride, sulfate and other scaling anions. It relieves membrane scaling and degradation, extending the service life of RO and ED membranes. It fits the pre-purification of circulating process water in chemical and surface treatment workshops.
Anion purification of electrolytic solution
In electrolytic metal production lines, D201 eliminates harmful anionic impurities such as nitrate and phosphate from electrolyte. Stable adsorption performance prevents impurity accumulation in the bath, stabilizes electrolytic current efficiency and enhances the surface quality of electroplated or electrolytic metal products.
Decontamination of flue gas desulfurization wastewater
For FGD wastewater from power plants, D201 captures heavy metal complex anions, thiosulfate and residual organic components. It helps meet discharge standards for desulfurization wastewater. Its good anti-pollution property adapts to complicated water quality with fluctuating impurity concentrations.
Recovery of organic acid from dilute aqueous solution
D201 can selectively adsorb water-soluble organic acids from dilute fermentation or synthesis effluent. Target organic acids can be eluted and recycled. This method cuts waste discharge and lowers raw material cost for organic acid manufacturers, realizing resource recycling.
