The Macroporous Adsorption Resin AB-8 is a high-performance material designed for efficient separation and purification processes. Developed by Hebei Lijiang Biotechnology Co., Ltd., this resin is ideal for applications requiring the extraction of water-soluble and weakly polar substances, such as stevioside and alkaloids. Its unique properties make it a preferred choice in industries ranging from pharmaceuticals to environmental protection.
Product Features
The Macroporous Adsorption Resin AB-8 offers several advantages that set it apart from conventional adsorbents:
- Easy Observation: The milky white or light yellow appearance simplifies the monitoring of colored organic compounds during processing.
- Chemical Stability: Insoluble in acids, alkalis, and organic solvents, ensuring versatility in solvent selection for adsorption and desorption.
- High Selectivity: Demonstrates strong affinity for organic matter, unaffected by the presence of inorganic salts.
- Regenerable: Can be efficiently regenerated using water, dilute acids, alkalis, or low-boiling solvents like methanol or ethanol.
- Durability: Excellent mechanical strength ensures a long service life, reducing replacement costs.

Applications in Water Purification and Separation
The Macroporous Adsorption Resin AB-8 is widely used in scenarios requiring the removal of impurities and the isolation of target compounds. Its applications include:
- Pharmaceutical Industry: Extraction and purification of alkaloids, glycosides, and other bioactive compounds from natural sources.
- Food and Beverage: Removal of pigments, heavy metals, and organic pollutants from water and food products.
- Environmental Protection: Treatment of industrial wastewater to eliminate organic contaminants and heavy metals.
- Chemical Industry: Separation of weakly polar substances from complex mixtures, such as in the production of synthetic resins.
Pretreatment and Regeneration
To ensure optimal performance, the resin requires proper pretreatment and periodic regeneration:
Pretreatment
1. Soak the resin in 10–20 cm of ethanol for 3–4 hours. Drain the solution and repeat the washing process until the effluent is clear.
2. Rinse thoroughly with water until no ethanol odor remains. This prepares the resin for general use.
Enhanced Regeneration
1. Soak the resin in 3–5% hydrochloric acid for 2–4 hours. Rinse with 5–7 times the volume of the acid solution.
2. Follow with a 5% sodium hydroxide solution using the same method.
3. Rinse with water until the pH of the effluent is neutral. This restores the resin’s adsorption capacity.
Precautions for Use
- Store the resin at 5–40°C to prevent freezing or mold growth.
- If the resin dries out, rehydrate it with ethanol before rinsing with water to avoid floating.
- Filter solutions before loading onto the resin to prevent impurity buildup and resin poisoning.
- Keep the resin submerged in water or a saturated saline/ethanol solution during storage to avoid contamination.
