The Macroporous Adsorption Resin AB-8 is a cutting-edge solution for water purification and organic compound separation. Developed by Hebei Lijiang Biotechnology Co., Ltd., this resin combines advanced polymer chemistry with practical engineering to deliver exceptional performance in industrial and environmental applications. This article provides an in-depth analysis of its features, technical specifications, and real-world utility.
Product Features
The AB-8 resin is designed with a unique combination of physical and chemical properties that make it ideal for complex purification processes. Its milky white opaque spherical beads ensure ease of observation during separation and purification, particularly when dealing with colored organic compounds. This visual clarity is critical in applications where monitoring the process is essential.
One of the standout features of the AB-8 resin is its chemical stability. It is insoluble in acids, alkalis, and organic solvents, allowing for flexible selection of adsorbents and desorbents. This versatility makes it suitable for a wide range of applications, from pharmaceuticals to environmental remediation.
The resin also exhibits high selectivity for organic matter, unaffected by the presence of inorganic salts. This characteristic is particularly valuable in scenarios where impurities are common, such as wastewater treatment or natural product extraction. Its mechanical strength ensures a long service life, reducing the need for frequent replacements and minimizing operational costs.

The AB-8 resin boasts a high specific surface area of 480 m²/g, enabling efficient adsorption of target compounds. Its macroporous structure allows for rapid mass transfer, making it ideal for large-scale industrial processes. The resin’s pore volume and porosity further enhance its capacity to retain and release substances effectively.
Applications and Use Cases
The AB-8 resin is widely used in the extraction and purification of water-soluble and weakly polar substances, such as stevioside, alkaloids, and flavonoids. Its weak polar nature makes it particularly effective for separating compounds that are difficult to isolate using conventional methods.
In the water purification industry, the resin is employed to remove organic pollutants, heavy metals, and other contaminants. Its regeneration capabilities allow for multiple cycles of use, reducing waste and operational costs. For example, the resin can be regenerated using ethanol, methanol, or dilute acids, ensuring long-term sustainability.
Another key application is in the pharmaceutical industry, where it is used to purify active ingredients from natural sources. Its selectivity ensures that only the desired compounds are retained, while impurities are washed away. This precision is critical in producing high-purity pharmaceuticals.

Preparation and Maintenance
Before use, the AB-8 resin requires proper pretreatment to remove inert solvents. This involves soaking the resin in ethanol for 3–4 hours, followed by thorough washing with water until no ethanol odor remains. This process ensures optimal performance and prevents contamination during operation.
For enhanced regeneration, the resin can be treated with 3–5% hydrochloric acid or 5% sodium hydroxide solutions. This step is crucial for restoring its adsorption capacity after prolonged use. After regeneration, the resin should be rinsed with clean water until the pH of the effluent is neutral, ensuring it is ready for the next cycle.
Proper storage is essential to maintain the resin’s integrity. It should be kept in a temperature-controlled environment (5–40°C) to prevent freezing or mold growth. If the resin dries out, it can be rehydrated by soaking in ethanol before cleaning with water. Regular maintenance, such as periodic washing and storage in saturated saline or ethanol, further extends its lifespan.
