Macroporous Adsorption Resin AB-8 is a cutting-edge solution for the separation and purification of water-soluble and weakly polar substances, such as stevioside and alkaloids. Developed by Hebei Lijiang Biotechnology Co., Ltd., this resin is engineered to deliver exceptional performance in industrial and laboratory settings. Its unique properties make it a preferred choice for applications ranging from pharmaceuticals to environmental remediation.
Product Features
The Macroporous Adsorption Resin AB-8 boasts a range of features that set it apart from conventional adsorbents. Its milky white opaque spherical beads ensure ease of observation during processing, particularly when handling colored organic compounds. The resin’s weak polar structure (PSD) allows for selective adsorption of target molecules, while its high specific surface area (≥480 m²/g) enhances adsorption capacity (≥45 mg/g). This combination of attributes ensures efficient separation and purification processes.
One of the standout features of AB-8 is its chemical stability. It remains insoluble in acids, alkalis, and organic solvents, making it highly versatile for various applications. This stability also simplifies the selection of adsorbents and desorbents, reducing operational complexity. Additionally, the resin exhibits good mechanical strength, ensuring a long service life even under demanding conditions.
The resin’s easy regeneration capability is another key advantage. It can be regenerated using water, dilute acids, alkalis, or low-boiling organic solvents like ethanol or acetone. This not only reduces costs but also minimizes environmental impact. For instance, water purification resin applications benefit from this feature, as it allows for repeated use without significant loss of performance.

Its ability to selectively adsorb weakly polar substances makes it ideal for water purification resin applications, where it effectively removes contaminants such as heavy metals and organic pollutants. In the pharmaceutical sector, it is employed for the extraction and purification of alkaloids and other bioactive compounds.
In food and beverage processing, AB-8 is used to decolorize and purify natural extracts, such as stevioside from Stevia leaves. Its anion chromatography resin properties also make it suitable for separating charged molecules in complex mixtures. For example, in environmental remediation, the resin can be used to treat industrial wastewater, ensuring compliance with regulatory standards.
The resin’s compatibility with various solvents allows it to be adapted for different applications. Whether in a laboratory setting or large-scale industrial operations, AB-8’s versatility ensures it meets diverse needs. Its easy regeneration further enhances its applicability in continuous processes, reducing downtime and operational costs.

Preparation and Maintenance
Proper preparation and maintenance are critical to maximizing the performance of Macroporous Adsorption Resin AB-8. Before use, the resin must be pretreated to remove inert solvents. This involves soaking the resin in ethanol for 3–4 hours, followed by thorough rinsing with water until the effluent is clear. For enhanced regeneration, the resin can be treated with dilute acids or alkalis, depending on the application.
Storage conditions are equally important. The resin should be kept in a temperature range of 5–40°C to prevent freezing or microbial growth. If the resin dries out, it should be rehydrated using ethanol before rinsing with water. Regular cleaning and proper storage ensure the resin maintains its adsorption capacity and mechanical integrity over time.
