The Macroporous Adsorption Resin AB-8 is a cutting-edge material engineered for efficient separation, purification, and extraction processes in various industries. Developed by Hebei Lijiang Biotechnology Co., Ltd., this resin is a weakly polar styrene-based copolymer with a unique structure that enables it to adsorb and retain water-soluble and weakly polar substances effectively. This article delves into the product's technical specifications, features, applications, and the company's expertise, while incorporating authoritative references from the National Institute of Standards and Technology (NIST) to ensure credibility and reliability.
The Macroporous Adsorption Resin AB-8 is a macroporous adsorption resin designed for the extraction, separation, and purification of organic compounds, particularly those with low polarity. Its structure is based on a polystyrene-divinylbenzene (PSD) matrix, with a weakly polar nature that allows it to selectively adsorb target molecules while resisting interference from inorganic salts. This resin is widely used in pharmaceuticals, food processing, environmental remediation, and chemical synthesis due to its high adsorption capacity and stability.
Key features of the AB-8 resin include:
| Parameter | Specification |
|---|---|
| Appearance | Milky white opaque spherical beads |
| Resin Structure | Polystyrene-Divinylbenzene (PSD) |
| Polarity | Weakly 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 Macroporous Adsorption Resin AB-8 is particularly effective in the following applications:
The resin is used to extract and purify bioactive compounds such as alkaloids and stevioside from natural sources. Its ability to separate weakly polar substances makes it ideal for isolating pharmaceutical intermediates and active ingredients. According to NIST guidelines on analytical standards, the resin's performance aligns with industry requirements for precision and reproducibility in drug development.
In the food industry, AB-8 resin is employed to remove impurities, colorants, and unwanted compounds from liquid solutions. For example, it is used in the purification of natural sweeteners and the clarification of fruit juices. Its chemical stability ensures that it does not leach harmful substances into the final product, meeting food safety standards.
The resin's high adsorption capacity makes it suitable for removing organic pollutants from wastewater. It can effectively capture contaminants such as dyes, pesticides, and industrial chemicals, contributing to sustainable water treatment solutions. NIST's research on environmental measurement standards underscores the importance of materials like AB-8 in addressing water quality challenges.
AB-8 resin is utilized in the separation of reaction mixtures, enabling the recovery of valuable by-products and the purification of final compounds. Its resistance to harsh chemical conditions allows it to be used in a variety of synthesis processes, from organic chemistry to polymer production.
Proper preparation and regeneration are critical to maintaining the resin's performance:
Before use, the resin must be pretreated to remove inert solvents. The process involves soaking the resin in ethanol (10–20 cm above the resin layer) for 3–4 hours, followed by repeated washing with water until the effluent is clear. This ensures the resin is in a wet state and ready for adsorption.
When the resin's adsorption capacity decreases, it can be regenerated using a 3–5% hydrochloric acid solution, followed by a 5–7 times volume rinse. Subsequent treatment with a 5% sodium hydroxide solution and thorough washing with water restores the resin's functionality. This process is detailed in the product documentation.
