The Macroporous Adsorption Resin AB-8 has emerged as a cornerstone in modern separation and purification processes. Developed by Hebei Lijiang Biotechnology Co., Ltd., this resin combines advanced polymer chemistry with tailored physical properties to address a wide range of industrial and scientific challenges. This article delves into the product’s features, technical specifications, applications, and the company’s commitment to innovation, supported by authoritative references from the National Institute of Standards and Technology (NIST).
Product Overview
Macroporous Adsorption Resin AB-8 is a styrene-type weakly polar copolymer synthesized using divinylbenzene as a crosslinking agent, methyl acrylate as a monomer, and toluene as a porogen. Its unique structure enables it to effectively adsorb and separate water-soluble and weakly polar substances such as stevioside, alkaloids, and other organic compounds. The resin’s macroporous network, combined with its high surface area and controlled pore size, makes it an ideal choice for applications in pharmaceuticals, food processing, environmental remediation, and chemical synthesis.
Key Features of AB-8 Resin
- Visual Clarity: The milky white or light yellow appearance facilitates easy monitoring of the separation process, particularly when dealing with colored organic compounds.
- Chemical Stability: Insoluble in acids, alkalis, and organic solvents, the resin offers versatility in selecting adsorbents and desorbents. This stability ensures long-term performance in harsh chemical environments.
- High Selectivity: AB-8 exhibits strong affinity for organic matter, remaining unaffected by the presence of inorganic salts, which is critical for purifying complex mixtures.
- Easy Regeneration: The resin can be efficiently regenerated using water, dilute acids, alkalis, or low-boiling organic solvents like methanol or ethanol, reducing operational costs and downtime.
- Durability: With excellent mechanical strength, AB-8 maintains its structural integrity over extended periods, ensuring consistent performance in industrial applications.

Applications in Industry and Research
The versatility of AB-8 resin is evident in its diverse applications:
- Pharmaceuticals: Used for the extraction and purification of alkaloids, glycosides, and other bioactive compounds from natural sources.
- Food and Beverage: Ideal for decolorization, deodorization, and removal of impurities in sugar, syrups, and edible oils.
- Environmental Protection: Effective in treating wastewater and removing organic pollutants, aligning with NIST’s guidelines for sustainable technologies (NIST).
- Chemical Industry: Facilitates the separation of organic compounds in synthesis processes, enhancing product purity and yield.
Preparation and Regeneration Procedures
Proper handling ensures optimal performance of AB-8 resin:
Pre-Treatment
Industrial-grade resins require pretreatment to remove inert solvents. Follow these steps:
- Soak the resin in 10–20 cm of ethanol for 3–4 hours, then drain the solution.
- Repeat washing with ethanol until the effluent is clear, followed by thorough rinsing with water until no ethanol smell remains.
Enhanced Regeneration
When adsorption capacity declines, perform the following:
- Soak the resin in 3–5% hydrochloric acid for 2–4 hours, then rinse with 5–7 times the volume of the solution.
- Repeat the process with 5% sodium hydroxide, ensuring the pH of the effluent is neutral before reuse.
Storage and Handling Precautions
- Store at 5–40°C to prevent freezing or microbial growth.
- If the resin dries, rehydrate it with ethanol before cleaning with water to avoid floating.
- Ensure feed solutions are filtered and clarified to prevent resin contamination.
- Keep the resin submerged in water or saturated saline/ethanol during long-term storage.
