Introduction
The Macroporous Adsorption Resin AB-8 is a cutting-edge material designed for advanced separation and purification processes. Developed by Hebei Lijiang Biotechnology Co., Ltd., this resin is widely used in the pharmaceutical, food, and environmental industries due to its exceptional performance and versatility. This article delves into the product’s features, technical specifications, applications, and the company’s commitment to innovation.
Key Features of Macroporous Adsorption Resin AB-8
The AB-8 resin is engineered to deliver optimal results in various separation processes. Its unique properties make it a preferred choice for industries requiring high-purity outputs. Here are the standout features:
- Color and Visibility: The milky white or light yellow appearance allows for easy observation during the separation of colored organic compounds.
- Chemical Stability: Insoluble in acids, alkalis, and organic solvents, ensuring flexibility in selecting adsorbents and desorbents.
- High Selectivity: Demonstrates strong affinity for organic matter, unaffected by inorganic salts, making it ideal for complex mixtures.
- Easy Regeneration: Can be regenerated using water, dilute acids, alkalis, or low-boiling solvents like methanol or ethanol, extending its lifespan.
- Robust Mechanical Strength: Ensures long-term durability and consistent performance under operational conditions.
Technical Specifications
The AB-8 resin’s performance is defined by its precise technical parameters. Below is a detailed specification table:
| 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% |
| Specific Surface Area | ≥480 m²/g |
| Adsorption Capacity | ≥45 mg/g |
These specifications highlight the resin’s ability to efficiently adsorb and separate target compounds, ensuring high purity and yield in industrial applications.
Applications of AB-8 Resin
The versatility of the AB-8 resin makes it suitable for a wide range of applications, including:
- Pharmaceutical Industry: Extraction and purification of alkaloids, stevioside, and other water-soluble compounds.
- Food and Beverage: Removal of impurities and colorants from natural extracts, enhancing product clarity and stability.
- Environmental Protection: Treatment of wastewater to remove organic pollutants and heavy metals.
- Chemical Industry: Separation of organic compounds from complex mixtures, improving process efficiency.
Its ability to handle both polar and non-polar substances makes it a valuable tool in diverse industrial settings.
Preparation and Regeneration
To ensure optimal performance, proper pretreatment and regeneration are essential:
Pretreatment
Industrial-grade resins require pretreatment to remove inert solvents. Follow these steps:
- Soak the resin in 10–20 cm of ethanol for 3–4 hours.
- Drain the solution and repeat washing until the effluent is clear.
- Rinse with clean water until no ethanol odor remains.
Enhanced Regeneration
When the resin’s adsorption capacity declines, perform the following regeneration steps:
- Soak in 3–5% hydrochloric acid for 2–4 hours, then rinse with water until neutral pH.
- Soak in 5% sodium hydroxide solution for 2–4 hours, followed by thorough rinsing with water.
Regular regeneration ensures long-term efficiency and reduces operational costs.
Precautions for Use and Storage
To maintain the resin’s integrity and performance, follow these guidelines:
- Store at 5–40°C to prevent freezing or mold growth.
- Avoid direct water injection if the resin dries out; instead, rehydrate with ethanol before rinsing.
- Filter solutions before loading to prevent resin contamination.
- Store wet resin in clean water or saturated saline/ethanol for long-term preservation.
