Product Features and Advantages
The Macroporous Adsorption Resin AB-8 is a styrene-type weak polar copolymer, composed of a crosslinking agent (divinylbenzene), monomer (methyl acrylate), and porogen (toluene, etc.). Its design ensures stability and efficiency in various applications. Key features include:
- Color and Observability: The milky white or light yellow appearance facilitates easy observation during processing, particularly when separating colored organic compounds.
- Chemical Stability: The resin is insoluble in acids, alkalis, and organic solvents, allowing for flexible selection of adsorbents and desorbents.
- High Selectivity: It exhibits strong selectivity for organic matter, unaffected by inorganic salts, making it ideal for complex mixtures.
- Easy Regeneration: The resin can be regenerated using water, dilute acids, alkalis, or low-boiling organic solvents like methanol or ethanol, ensuring long-term cost-effectiveness.
- Robust Mechanical Strength: Its durability ensures a prolonged service life, reducing the need for frequent replacements.
These features make the AB-8 resin a preferred choice for industries requiring reliable and efficient separation solutions, such as pharmaceuticals, food processing, and environmental protection.

Preparation and Regeneration
Proper preparation and regeneration are essential to maintain the Macroporous Adsorption Resin AB-8‘s performance. The pretreatment process involves soaking the resin in ethanol and subsequent washing with water to remove residual solvents. For enhanced regeneration, the resin can be treated with hydrochloric acid or sodium hydroxide solutions, followed by thorough rinsing to neutralize pH levels.
Key steps for regeneration include:
- Soak the resin in 3–5% hydrochloric acid for 2–4 hours.
- Rinse with 5–7 times the volume of hydrochloric acid solution.
- Soak in 5% sodium hydroxide for 2–4 hours.
- Rinse with 5–7 times the volume of sodium hydroxide solution until neutral pH is achieved.
Following these steps ensures the resin’s longevity and optimal performance.
Precautions and Storage
To preserve the Macroporous Adsorption Resin AB-8‘s integrity, the following precautions should be observed:
- Store the resin at temperatures between 5–40°C to prevent freezing or mildew.
- Avoid direct water injection if the resin dries out; instead, use ethanol to rehydrate it before washing with water.
- Pre-filter solutions before use to prevent impurities from clogging the resin column.
- Store the resin in soaked clean water or saturated saline/ethanol for long-term preservation.
Adhering to these guidelines ensures the resin’s effectiveness and extends its service life.
