D301 styrene-DVB anion exchange resin
,weak-base anion exchange resin free base
,styrene-DVB ion exchange resin
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.

Typical Application Fields
D301 is a macroporous weak‑base anion exchange resin functionalized with tertiary amine groups. It delivers remarkable organic fouling resistance and low‑consumption regeneration. Besides aqueous‑phase operations, it can also serve selected organic‑solvent working conditions.
-
Sugar Processing & Refining Deployed in sugar‑manufacturing workflows for syrup decolorization and ash elimination. It adsorb color‑forming organics and acidic anions to enhance syrup clarity and guarantee end‑product quality of sugar goods.
-
Wastewater Disposal for Electroplating Sector Carry out advanced purification for chromium‑laden wastewater from electroplating workshops. It selectively captures hexavalent chromium ions to recover heavy‑metal resources and help effluent meet regulatory discharge limits.
-
Desalination & Industrial Pure‑Water Preparation Act as key filter medium in water‑treatment workflows to eliminate free mineral acids, silicate radicals and large‑molecular organic contaminants. When paired with cation resins, it produces industrial‑grade pure water and performs especially well for influent water rich in organics.
-
Leachate Purification in Hydrometallurgy Applied for purification and separation of rare‑metal and precious‑metal leach liquors within hydrometallurgical workflows. It traps diverse metal‑complex anions from feed solutions to realize separation and enrichment of target metals.
-
Feed‑Liquid Treatment for Bio‑fermentation Achieve acid removal and impurity decolorization for fermentation broths. It strips organic acids and large‑molecular colored by‑products generated during fermentation, lowering purification burden for downstream procedures.
-
Impurity Removal in Organic‑solvent Systems Fit for certain non‑aqueous‑phase processes to get rid of acidic impurity components mixed inside organic‑solvent media.
