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.

Applications

High‑speed mixed‑bed water deionization: Suited for large‑volume mixed‑bed purification units commonly adopted by power plants and ultra‑pure‑water‑related manufacturing sectors. Matched with macroporous strong‑acid cation resin, D201 delivers fine polishing treatment for boiler condensate water and strips residual anionic impurities, securing consistent high‑purity water output. Thanks to outstanding resistance to osmotic pressure impact and great wear‑resistant mechanical performance, the resin can sustain reliable long‑run operation under high linear flow rates without frequent performance degradation.

Industrial wastewater purification: Different from gel‑type ion exchange materials prone to organic fouling, D201 features a unique macroporous polymer skeleton. It is capable of adsorbing routine inorganic anions as well as large‑molecule organic pollutants contained in waste water from chemical production, electroplating workshops and petrochemical plants. It helps cut down total pollutant levels in effluent to satisfy industrial emission standards, and maintains stable treating capacity for inlet water rich in organic foulants.

Rare‑element separation in hydrometallurgy: D201 is extensively applied to handle leachate generated in wet‑metallurgical production flows. Faced with complicated feed solutions full of interfering competing ions, it can adsorb, separate and enrich target anionic complexes of rare metals. It streamlines follow‑up metal recycling procedures, raises finished‑product recovery rate, and cuts down dosage of chemical agents in rare‑element separation processes.

Recycling of heavy‑metal resources: For factory effluent and electroplating waste water carrying heavy‑metal anionic complexes, D201 realizes targeted selective adsorption. Rather than only removing toxic heavy metals to satisfy discharge regulations, the resin enables resource recycling via elution and regeneration operations. It lowers the generation of hazardous solid waste and facilitates circular‑economy manufacturing for metal processing enterprises.

Regenerable solid base catalyst for organic synthesis: D201 can act as recyclable heterogeneous strong‑base catalyst for multiple organic synthesis reactions. Its stable macroporous cross‑linked structure guarantees steady catalytic activity even within non‑aqueous reaction environments. Compared with traditional liquid alkaline catalysts, D201 greatly eases subsequent separation procedures, decreases waste liquor generation, and supports repeated regeneration cycles to help chemical manufacturers bring down comprehensive running expenses.
