The Macroporous Adsorption Resin AB-8 is a high-performance adsorbent designed for the extraction, separation, and purification of water-soluble and weakly polar substances. Developed by Hebei Lijiang Biotechnology Co., Ltd., this resin is widely used in pharmaceuticals, food processing, and environmental protection industries. Its unique properties make it a preferred choice for applications requiring precision and efficiency in separation processes.
Product Features
The Macroporous Adsorption Resin AB-8 stands out due to its exceptional features, which enhance its functionality and usability in various industrial applications. Here are some of its key characteristics:
- Color and Visibility: The resin’s milky white or light yellow appearance simplifies the observation of colored organic compounds during processing, making it easier to monitor separation and purification steps.
- Chemical Stability: It exhibits remarkable stability in acidic, alkaline, and organic solvent environments, allowing for flexible selection of adsorbents and desorbents. This stability ensures long-term performance without degradation.
- High Selectivity: The resin demonstrates strong selectivity for organic compounds, effectively excluding interference from inorganic salts. This makes it ideal for purifying complex mixtures.
- Easy Regeneration: The resin can be regenerated using simple agents like water, dilute acids, alkalis, or low-boiling organic solvents (e.g., methanol, ethanol, acetone). This reduces operational costs and extends the resin’s service life.
- Robust Mechanical Strength: With excellent mechanical properties, the resin maintains its structural integrity under normal operating conditions, ensuring a long service life and minimizing replacement frequency.

Preparation and Regeneration
Proper preparation and regeneration are critical to maintaining the Macroporous Adsorption Resin AB-8‘s performance. Here’s a guide for optimal usage:
Resin Pretreatment
Before use, the resin must be pretreated to remove inert solvents. The process involves:
- Soaking the resin in 10–20 cm of ethanol for 3–4 hours, followed by draining the solution.
- Repeated washing with ethanol until the effluent is clear, then rinsing with clean water until the ethanol smell is gone.
Enhanced Regeneration
If the resin’s adsorption capacity declines, perform the following steps:
- Soak the resin in 3–5% hydrochloric acid for 2–4 hours, then rinse with 5–7 times the volume of the acid solution.
- Repeat the process with 5% sodium hydroxide solution, ensuring thorough rinsing until the effluent is neutral.
Storage and Handling Precautions
To ensure the longevity and effectiveness of the Macroporous Adsorption Resin AB-8, follow these guidelines:
- Store the resin at temperatures between 5–40°C to prevent freezing or mildew.
- Avoid direct water injection if the resin dries out; instead, rehydrate it with ethanol before cleaning with water.
- Filter and clarify the solution before use to prevent impurities from clogging the resin column.
- Keep the resin submerged in clean water or saturated saline/ethanol when not in use to prevent contamination.
