Introduction to Macroporous Adsorption Resin AB-8
The Macroporous Adsorption Resin AB-8 is a cutting-edge material designed for efficient separation and purification processes in various industries. Developed by Hebei Lijiang Biotechnology Co., Ltd., this resin is a weakly polar styrene-based copolymer, making it ideal for extracting and purifying water-soluble and weakly polar substances such as stevioside and alkaloids. Its unique properties, including high adsorption capacity and stability, position it as a preferred choice for water purification and industrial applications.
Key Features and Advantages
The Macroporous Adsorption Resin AB-8 offers a range of features that enhance its utility in diverse scenarios:
- Visual Clarity: The resin’s milky white or light yellow appearance facilitates easy monitoring of processing, particularly when separating colored organic compounds.
- Chemical Stability: It remains insoluble in acids, alkalis, and organic solvents, allowing flexibility in selecting adsorbents and desorbents.
- High Selectivity: The resin demonstrates excellent selectivity for organic matter, unaffected by the presence of inorganic salts.
- Easy Regeneration: It can be regenerated using water, dilute acids, alkalis, or low-boiling organic solvents like methanol or ethanol.
- Durability: The resin’s robust mechanical strength ensures a long service life under normal operating conditions.

Pretreatment and Regeneration Procedures
To ensure optimal performance, the Macroporous Adsorption Resin AB-8 requires proper pretreatment and regeneration:
Pretreatment
Industrial-grade resins are typically stored in inert solvents. To prepare the resin for use:
- Add 10–20 cm of ethanol above the resin layer and soak for 3–4 hours.
- Drain the soaking solution and repeat the washing process until the effluent is clear.
- Rinse thoroughly with clean water until no ethanol smell remains.
Enhanced Regeneration
When the resin’s adsorption capacity decreases or it becomes contaminated:
- Soak the resin in 3–5% hydrochloric acid for 2–4 hours.
- Rinse with 5–7 times the volume of hydrochloric acid solution until neutral pH is achieved.
- Repeat the process with 5% sodium hydroxide solution, followed by thorough water rinsing.
Precautions for Storage and Handling
To maintain the resin’s integrity and performance:
- Store the resin at 5–40°C to prevent freezing or mildew.
- If the resin dries out, rehydrate it using ethanol before rinsing with water.
- Ensure solutions are filtered before use to avoid resin contamination.
- Store the resin in water or saturated saline/ethanol if not in use for extended periods.
