Developed by Hebei Lijiang Biotechnology Co., Ltd., this resin combines advanced polymer technology with exceptional performance characteristics, making it a preferred choice in industries ranging from pharmaceuticals to environmental engineering. This article explores the product’s features, technical specifications, applications, and the company’s expertise, providing a comprehensive overview of its value in modern industrial processes.
Product Features: Precision and Performance
The Macroporous Adsorption Resin AB-8 is engineered to deliver superior efficiency in separation and purification tasks. Its milky white or light yellow appearance simplifies the observation of colored organic compounds during processing, ensuring transparency and ease of operation. This resin is chemically stable, remaining insoluble in acids, alkalis, and organic solvents, which allows for flexible selection of adsorbents and desorbents. This stability is critical in applications where harsh chemical environments are common.
One of the standout features of AB-8 is its strong selectivity for organic matter, even in the presence of inorganic salts. This makes it ideal for purifying complex mixtures where impurities could interfere with the desired outcome. Additionally, the resin’s easy regeneration capability enhances its cost-effectiveness. It can be regenerated using water, dilute acids, alkalis, or low-boiling organic solvents like methanol or ethanol, ensuring long-term usability without significant loss of performance.
The resin also boasts high mechanical strength, contributing to its durability and extended service life. This is particularly important in industrial settings where continuous operation is required. The combination of these features positions AB-8 as a reliable and versatile tool for a wide range of applications.

The Macroporous Adsorption Resin AB-8 is designed with a high specific surface area (≥480 m²/g) and large pore volume (0.73–0.77 ml/g), enabling it to efficiently adsorb and retain target compounds. Its average pore size of 13–14 nm ensures optimal accessibility for molecules of varying sizes, while its bulk density (0.65–0.70 g/ml) and real density (1.05–1.09 g/ml) contribute to its structural integrity and performance under operational conditions.
Applications: Versatile Use in Industrial Processes
Macroporous Adsorption Resin AB-8 is widely used in the extraction, separation, and purification of water-soluble and weakly polar substances. It is particularly effective in the isolation of stevioside (a natural sweetener) and alkaloids (such as those found in medicinal plants). Its ability to handle complex mixtures makes it a valuable tool in the pharmaceutical, food, and beverage industries.
In environmental engineering, AB-8 is employed for water purification to remove organic pollutants and contaminants. Its strong selectivity ensures that even trace amounts of harmful substances can be effectively captured, improving water quality. Additionally, the resin’s regeneration capability reduces waste and operational costs, aligning with sustainable industrial practices.
The resin’s chemical stability also makes it suitable for anion chromatography and other advanced separation techniques. Its compatibility with various solvents and its resistance to degradation under harsh conditions further expand its applicability in specialized processes.

Preparation and Regeneration: Ensuring Optimal Performance
To maximize the effectiveness of Macroporous Adsorption Resin AB-8, proper preparation and regeneration are essential. Before use, the resin should be soaked in ethanol (10–20 cm above the resin layer for 3–4 hours) to remove any inert solvents. After soaking, the solution should be drained, and the resin should be rinsed with water until the effluent is clear and free of ethanol odor.
When the resin’s adsorption capacity decreases or it becomes contaminated, enhanced regeneration is required. This involves soaking the resin in 3–5% hydrochloric acid for 2–4 hours, followed by rinsing with water until the pH is neutral. The resin is then soaked in 5% sodium hydroxide and rinsed again to restore its performance. Proper regeneration ensures the resin can be reused multiple times, reducing long-term costs.
Precautions: Ensuring Safety and Longevity
To maintain the performance and longevity of Macroporous Adsorption Resin AB-8, the following precautions should be observed:
- Storage: Keep the resin at temperatures between 5–40°C to prevent freezing or mildew. Avoid exposure to extreme temperatures during transportation and storage.
- Rehydration: If the resin dries out, avoid direct water injection. Instead, rehydrate it with ethanol and then rinse thoroughly with water to restore its wet state.
- Purification: Before loading the resin, ensure the solution is filtered and clarified to remove impurities that could cause resin poisoning.
- Storage After Use: After washing, store the resin in clean water or a saturated saline/ethanol solution to prevent contamination and maintain its activity.
