Macroporous Adsorption Resin AB-8 is a cutting-edge material designed for the efficient extraction, separation, and purification of water-soluble and weakly polar substances. Developed by Hebei Lijiang Biotechnology Co., Ltd., this resin combines advanced polymer chemistry with practical application features to meet the demands of modern industrial and scientific processes. Whether in pharmaceuticals, food processing, or environmental technology, AB-8 offers a reliable and cost-effective solution for complex separation challenges.
Product Features and Advantages
AB-8 is a weakly polar macroporous adsorption resin based on a styrene-divinylbenzene copolymer matrix. Its unique properties make it an ideal choice for a wide range of applications. Below are the key features and advantages of this resin:
- Visual Convenience: The milky white or light yellow appearance allows for easy monitoring of the separation process, particularly when dealing with colored organic compounds.
- Chemical Stability: AB-8 is insoluble in acids, alkalis, and organic solvents, providing flexibility in selecting adsorbents and desorbents for various applications.
- High Selectivity: The resin exhibits strong selectivity for organic matter, remaining unaffected by the presence of inorganic salts, which simplifies purification workflows.
- Easy Regeneration: AB-8 can be regenerated using water, dilute acids, alkalis, or low-boiling organic solvents like methanol or ethanol, ensuring long-term cost-effectiveness.
- Excellent Mechanical Strength: The resin maintains its structural integrity under repeated use, offering a long service life and reducing the need for frequent replacements.

Applications and Use Cases
AB-8 is widely used in industries requiring the extraction and purification of organic compounds. Key applications include:
- Pharmaceuticals: Isolation of alkaloids, glycosides, and other bioactive compounds from natural sources.
- Food Industry: Purification of food additives, flavorings, and sweeteners like stevioside.
- Environmental Technology: Removal of pollutants and organic contaminants from water and wastewater.
- Chemical Processing: Separation of organic compounds from complex mixtures in industrial settings.
The resin’s versatility is further enhanced by its compatibility with various solvents and its ability to withstand harsh chemical environments. For example, AB-8 is commonly used in anion chromatography resin applications, where its weak polarity allows for precise separation of charged molecules.
Preparation and Regeneration
Proper preparation and regeneration are critical to maintaining the performance of AB-8. Here’s a step-by-step guide:
Resin Pretreatment
Before use, the resin must be pretreated to remove residual solvents and ensure optimal performance:
- Soak the resin in 10–20 cm of ethanol for 3–4 hours.
- Drain the solution and repeat washing until the effluent is clear.
- Rinse with clean water until no ethanol odor remains.
Enhanced Regeneration
If the resin’s adsorption capacity decreases over time, follow these steps for regeneration:
- Soak the resin in 3–5% hydrochloric acid for 2–4 hours.
- Rinse with 5–7 times the resin volume of hydrochloric acid solution.
- Repeat the process with 5% sodium hydroxide solution.
- Finally, rinse with water until the pH of the effluent is neutral.
For detailed instructions, refer to the product manual.
Storage and Handling
To ensure the longevity of AB-8, proper storage and handling are essential:
- Store the resin at 5–40°C to prevent freezing or microbial growth.
- If the resin dries out, rehydrate it with ethanol before rinsing with water.
- Before loading, filter the solution to remove impurities and prevent resin poisoning.
- Store the resin in water, saline, or ethanol when not in use to maintain its stability.
