D301 weak-base anion resin
,anion resin for wastewater treatment
,ion exchange resin acid 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.

Main Application Fields
D301 is macroporous weak‑base anion exchange resin with three‑dimensional macroporous network and tertiary amine functional groups. It features superior fouling resistance, high regeneration efficiency and low regenerant consumption. Besides water treatment, it is applicable for purification of certain organic solvent materials, covering wastewater remediation, material purification and solution refining.

Sugar Liquor Purification in Sugar Industry
Process neutralized and clarified syrup during beet sugar and cane sugar production. The resin adsorbs colored colloids, organic acids and acidic ash impurities, reduces syrup color value, cuts the dosage of activated carbon, improves sugar quality and optimizes overall production cost.
-
Recovery & Treatment of Chromium‑Containing Electroplating Wastewater
Treat wastewater generated from electroplating processes. It performs selective adsorption on chromate and dichromate anions. Chromium components can be recovered for resource recycling, meanwhile effluent can reach discharge standards. It fits wastewater treatment and reclaimed‑water reuse projects for electroplating plants.
-
Industrial Pure Water Preparation for High‑Organic Raw Water
When dealing with surface water and groundwater rich in humus and organics, D301 works together with strong‑acid cation resin. It removes silicate ions, free acids and macromolecular organic pollutants to produce demineralized water for process water supply and circulating makeup water in factories.
-
Solution Purification for Hydrometallurgy
Treat metal leachate in hydrometallurgical processes. It adsorbs and separates rare‑metal and precious‑metal components existing as complex anions. Target metals get enriched while impurity anions are removed, simplifying downstream extraction and precipitation steps.
-
Pre‑Treatment & Refining for Fermentation Broth
Used for pre‑treatment of various bio‑fermentation liquors. It eliminates organic acids, pigments and high‑molecular by‑products generated in fermentation. Color and acidity of feed liquid are lowered to reduce workload of filtration, crystallization and extraction, and improve recovery rate of target products.
-
Removal of Acidic Impurities for Non‑Aqueous Materials
Capable of working under defined organic‑solvent conditions to eliminate acidic impurities mixed in organic materials. It realizes material purification for non‑aqueous phases and fits deacidification processes for selected fine‑chemical liquids.
