Macroporous Adsorption Resin AB-8 is a high-performance, professional-grade adsorbent engineered for the precise separation and purification of colored organic compounds. Featuring a unique macroporous structure and weak polarity, this resin is specifically designed to provide exceptional selectivity for organic matter, ensuring high-purity recovery and efficient removal of impurities from complex solutions.
With its superior mechanical strength and chemical stability, AB-8 remains insoluble in acids, alkalis, and organic solvents. This versatility allows for flexible regeneration using water, dilute acids/alkalis, or low-boiling organic solvents like methanol and ethanol, making it an ideal choice for industrial-scale hydrometallurgy and chemical synthesis applications where long-term durability is critical.

|---|---|---|---|
| Average Pore Size | 13-14 nm | Pore Volume | 0.73-0.77 ml/g |
| Specific Surface Area | ≥480 m²/g | Adsorption Capacity | ≥45 mg/g |
| Bulk Density | 0.65-0.70 g/ml | Real Density | 1.05-1.09 g/ml |
| Moisture Content | 65%~75% | Porosity | 42%~46% |
Insoluble in any acid, alkali, and organic solvent, ensuring stability across diverse processing environments.
Excellent mechanical strength minimizes bead attrition, significantly prolonging the operational lifespan.
Strong affinity for organic matter, remaining unaffected by the presence of inorganic salts in the solution.
The milky white/light yellow color facilitates easy observation of purification and separation processes.
Easily regenerated using water, dilute acids, or solvents like acetone and ethanol for cost-effective reuse.
Deeply processed "Net Grade" resin allows for direct column loading without extensive pretreatment.
Implement pre-filtration and clarification to prevent resin poisoning and ensure peak performance.
Perform water backwashing after packing to eliminate gas barriers and maintain adsorption flow.
Maintain storage temperatures between 5-40ºC to prevent freezing or mildew contamination.
Use ethanol impregnation to restore wet state if resin is exposed to air or loses water.
Store in clean water (changed regularly), saturated saline, or ethanol to prevent degradation.
Optimize desorption using methanol, ethanol, or acetone based on specific organic compound needs.
| Performance Metric | Standard Resins | AB-8 Macroporous Resin |
|---|---|---|
| Operational Life | Short/Moderate | Extended (High Mechanical Strength) |
| Regeneration Cost | High (Specific Agents) | Low (Water/Common Solvents) |
| Selectivity | General | High (Specific to Organic Matter) |
| Pre-treatment Need | Extensive | Minimal (Net Grade Processed) |
| Purity Output | Standard | High (Professional Purification) |
AB-8 is primarily used for the separation, purification, and adsorption of colored organic compounds and organic matter in various chemical and pharmaceutical processes.
Regeneration can be achieved using water, dilute alkali, dilute acid, or low-boiling organic solvents such as methanol, ethanol, and acetone.
As a Net Grade resin, it is deeply processed and can be used directly. However, soaking in ethanol or double distilled water and backwashing is recommended for maximum stability.
Store it at 5-40ºC in clean water (replaced regularly), saturated saline, or ethanol to prevent freezing, mildew, and contamination.
Do not inject water directly as this may cause the resin to float. Instead, impregnate it with ethanol to restore the wet state before cleaning with water.
Ensure the feed solution undergoes impurity removal, filtration, and clarification before entering the resin column to avoid clogging and poisoning.
