D201 Macroporous Strongly Basic Styrene‑Based Anion Exchange Resin Chlorine Type High Exchange Capacity Anti‑Pollution Ion Resin

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.

• High‑speed mixed‑bed water treatment: This resin is well‑matched for large‑throughput mixed‑bed deionization systems applied in power generation stations and industrial ultrapure‑water manufacturing premises. Combined with macroporous strong‑acid cation exchange resin, it polishes condensate water and eliminates residual anionic contaminants so as to obtain stable high‑purity effluent. With outstanding anti‑osmotic‑shock characteristics and remarkable wear‑resisting mechanical properties, it can sustain long‑term continuous operation under high linear flow‑rate working conditions.
• Industrial wastewater treatment: Featuring a distinctive macroporous internal structure, the resin can absorb routine inorganic anions alongside high‑molecular‑weight organic contaminants coming from chemical, electroplating and petrochemical production lines. It lowers pollutant concentrations in wastewater to meet industrial effluent regulatory requirements. Moreover, it can cope with inlet water loaded with organic fouling substances, which would otherwise degrade the operating efficiency of gel‑type ion exchange resins.
• Rare metal extraction: It is widely put into service for processing leaching solutions produced in hydrometallurgical operations. In complicated feed solutions containing numerous interfering ions, it completes selective adsorption, segregation and concentration of target rare‑metal anionic complexes. The resin helps simplify downstream metal‑recovery processes, improve final product yields and reduce chemical reagent usage during rare‑element separation work.
• Heavy‑metal recovery: It selectively collects anionic complexes carrying heavy‑metal constituents from general‑manufacturing and electroplating wastewater streams. Beyond basic removal of toxic heavy metals for emission compliance, it realizes resource reutilization by means of elution and regeneration treatments. It minimizes the output of hazardous waste and promotes circular‑economy‑based manufacturing within metal‑processing enterprises.
• Strong alkaline solid catalysts: It acts as a reusable solid strong‑base catalyst suitable for various organic synthesis procedures. Relying on its dimensionally stable macroporous network, it maintains steady catalytic activity even in non‑aqueous reaction surroundings. When contrasted with liquid‑form alkaline catalysts, D201 simplifies separation tasks following chemical reactions, lessens waste‑liquid generation, and allows multiple regeneration cycles to lower overall operating costs for chemical manufacturers.
