D301 Macroporous Ion Exchange Resin for Organic Matter Removal

PRODUCT DESCRIPTION

This product is a weakly basic anion exchange resin featuring tertiary amine groups [-N(CH₃)₂] on a macroporous styrene-divinylbenzene copolymer. Its mild alkalinity enables effective removal of organic pigments, inorganic acids, and silicate ions in acidic and near-neutral media. It also adsorbs larger molecular impurities and performs well in non-aqueous solutions. This resin offers high regeneration efficiency, large exchange capacity, strong resistance to contamination, and excellent mechanical strength.

Basic Information

Application Overview

1. Syrup Purification for Sugar Manufacturing

   
   

   Applied in refining procedures of cane‑sugar and beet‑sugar production lines. It adsorbs colored macromolecules, colloidal contaminants and acidic ash contents to reduce syrup color intensity, relieve pressure on follow‑up processes and improve whiteness and storage stability of final sugar products.
2. Resource‑Oriented Treatment of Chromium‑Containing Electroplating Wastewater

   
   

   Used for treating wastewater discharged from electroplating workshops. Leveraging its selective adsorption property, the resin captures chromate anions. It enables recycling of chromium resources and brings treated effluent up to legal discharge standards, suitable for both water reuse and compliance discharge in electroplating plants.
3. Demineralized Water Production from High‑Organic Raw Water

   
   

   Combined with strong‑acid cation exchange resin for raw water with high organic loading. It removes silicate ions, free mineral acids and humus‑like macromolecular organics to produce demineralized process water for factory circulating water and industrial process supply.
4. Separation & Enrichment for Hydrometallurgical Leachate

   
   

   Processes metal leachate in hydrometallurgy. It adsorbs and separates rare‑metal and precious‑metal components existing as complex anions, realizing target‑metal enrichment for subsequent metal recovery steps.
5. Pre‑Treatment Purification for Bio‑Fermentation Broth

   
   

   Serves as pre‑treatment medium for fermentation liquor. It removes metabolically generated organic acids, pigments and high‑molecular by‑products via deacidification and decolorization, lowering the burden of downstream extraction and crystallization and boosting product yield.
6. Removal of Acidic Impurities in Selected Organic Media

   
   

   Beyond aqueous environments, this resin can be deployed in limited organic‑solvent surroundings to strip mixed‑in acidic impurities and realize material purification for non‑aqueous systems.
