Macroporous Adsorption Resin AB-8 is a cutting-edge adsorbent material designed for the efficient extraction, separation, and purification of water-soluble and weakly polar substances. Developed by Hebei Lijiang Biotechnology Co., Ltd., this resin combines advanced polymer chemistry with robust physical properties to deliver exceptional performance in various industrial and research settings. This article delves into the product’s core features, technical specifications, applications, and the company’s expertise, supported by authoritative references and detailed imagery.
Product Features and Advantages
The Macroporous Adsorption Resin AB-8 stands out for its unique combination of physical and chemical properties. Its milky white or light yellow appearance facilitates easy observation during processing, particularly when separating and purifying colored organic compounds. The resin’s weak polar structure ensures compatibility with a wide range of solvents and compounds, making it highly versatile for diverse applications.
One of the key advantages of AB-8 is its chemical stability. It is insoluble in acids, alkalis, and organic solvents, allowing for flexible selection of adsorbents and desorbents. This stability is critical in industrial processes where harsh chemical conditions are common. Additionally, the resin exhibits high selectivity for organic matter, remaining unaffected by the presence of inorganic salts—a significant benefit in complex mixtures.
Regeneration is another standout feature. The resin can be easily regenerated using water, dilute acids, alkalis, or low-boiling organic solvents such as methanol, ethanol, or acetone. This not only reduces operational costs but also extends the resin’s service life. The mechanical strength of AB-8 ensures long-term durability, making it suitable for continuous industrial use.
Technical Specifications and Performance
The technical specifications of Macroporous Adsorption Resin AB-8 are designed to meet the demands of high-efficiency separation processes. Below is a detailed table summarizing its key parameters:
| Parameter | Specification |
|---|---|
| Appearance | Milky white opaque spherical beads |
| Resin Structure | PSD (Polystyrene Divinylbenzene) |
| Polarity | Weak polar |
| Moisture Content | 65%–75% |
| Particle Size Range | (60–16 mesh) 0.3–1.25 mm ≥90% |
| Average Pore Size | 13–14 nm |
| Pore Volume | 0.73–0.77 ml/g |
| Porosity | 42%–46% |
| Real Density | 1.05–1.09 g/ml |
| Bulk Density | 0.65–0.70 g/ml |
| Specific Surface Area | ≥480 m²/g |
| Adsorption Capacity | ≥45 mg/g |
The resin’s high specific surface area (≥480 m²/g) and large pore volume (0.73–0.77 ml/g) enable it to adsorb a significant quantity of target compounds. Its average pore size of 13–14 nm ensures effective diffusion of molecules, while the bulk density (0.65–0.70 g/ml) contributes to its ease of handling in column chromatography and other separation techniques.
Applications in Industry and Research
The Macroporous Adsorption Resin AB-8 is widely used in the extraction, separation, and purification of water-soluble and weakly polar substances. Its applications span multiple industries, including pharmaceuticals, food and beverage, environmental protection, and biotechnology. For instance, it is ideal for isolating stevioside (a natural sweetener) and alkaloids (such as morphine and caffeine) from plant extracts.
In the water purification sector, AB-8 is employed to remove organic pollutants and impurities from industrial wastewater. Its selectivity and stability make it a preferred choice for treating complex aqueous solutions. Additionally, the resin is used in anion chromatography for the separation of charged molecules, leveraging its weak polar nature to interact with specific analytes.
The resin’s regenerability and long service life make it a cost-effective solution for large-scale operations. For example, in the pharmaceutical industry, AB-8 is utilized to purify active pharmaceutical ingredients (APIs) by adsorbing impurities and undesired by-products. Its mechanical strength ensures minimal degradation during repeated cycles, maintaining consistent performance over time.

Preparation and Regeneration of the Resin
Proper preparation and regeneration are critical to maximizing the performance of Macroporous Adsorption Resin AB-8. Before use, the resin must be pretreated to remove inert solvents and ensure optimal adsorption capacity. The process involves soaking the resin in ethanol (10–20 cm above the resin layer) for 3–4 hours, followed by draining the solution and washing with water until the effluent is clear.
For enhanced regeneration, the resin can be treated with 3–5% hydrochloric acid or 5% sodium hydroxide solutions. This method effectively removes accumulated impurities and restores the resin’s adsorption efficiency. After regeneration, the resin must be thoroughly rinsed with clean water until the pH of the effluent reaches neutrality.
Key precautions include storing the resin at 5–40°C to prevent freezing or microbial growth. If the resin dries out, it should be rehydrated with ethanol before cleaning with water. Additionally, pre-filtration of the feed solution is essential to avoid resin poisoning caused by particulate matter or impurities.
