Macroporous Adsorption Resin AB-8 - Hebei Lijiang Biotechnology Co., Ltd.|Water Purification&Industrial Separation

Macroporous Adsorption Resin AB-8 is a high-performance adsorbent designed for the extraction, separation, and purification of water-soluble and weakly polar substances. Developed by Hebei Lijiang Biotechnology Co., Ltd., this resin is widely used in industries such as pharmaceuticals, food processing, and environmental protection. Its unique properties make it an ideal choice for applications requiring efficient and selective adsorption.

Product Features

The Macroporous Adsorption Resin AB-8 offers several key features that distinguish it from other adsorbents:

• Easy Observation: The milky white or light yellow appearance allows for convenient processing and clear visualization of colored organic compounds during separation and purification.
• Chemical Stability: Insoluble in acids, alkalis, and organic solvents, this resin provides flexibility in selecting adsorbents and desorbents.
• High Selectivity: It exhibits strong selectivity for organic matter, remaining unaffected by the presence of inorganic salts.
• Easy Regeneration: The resin can be regenerated using water, dilute acids, alkalis, or low-boiling organic solvents like methanol, ethanol, or acetone.
• Durability: With excellent mechanical strength, the resin ensures a long service life under normal operating conditions.

Applications

The Macroporous Adsorption Resin AB-8 is suitable for a wide range of applications, including:

• Water Purification: Effective in removing organic pollutants and impurities from water, making it ideal for water purification resin systems.
• Pharmaceuticals: Used for the extraction and purification of bioactive compounds such as alkaloids and stevioside.
• Food Industry: Helps in the separation of flavor compounds and the removal of unwanted substances from food products.
• Environmental Protection: Applied in the treatment of industrial wastewater and the recovery of valuable substances from effluents.

Pretreatment and Regeneration

Proper pretreatment and regeneration are essential to maintain the performance of the Macroporous Adsorption Resin AB-8:

Pretreatment

Industrial-grade resins often contain inert solvents. To prepare the resin for use:

1. Soak the resin in 10–20 cm of ethanol for 3–4 hours.
2. Drain the soaking solution and repeat the washing process until the effluent is clear.
3. Rinse thoroughly with clean water until no ethanol odor remains.

Enhanced Regeneration

When the resin's adsorption capacity decreases, follow these steps for regeneration:

1. Soak the resin in 3–5% hydrochloric acid for 2–4 hours.
2. Rinse with 5–7 times the volume of hydrochloric acid solution until the pH is neutral.
3. Repeat the process with 5% sodium hydroxide solution, followed by thorough rinsing with water.

Precautions

To ensure optimal performance and longevity of the resin, follow these guidelines:

• Store the resin at 5–40°C to prevent freezing or mold growth.
• Avoid direct water injection if the resin dries out; instead, rehydrate it with ethanol before cleaning.
• Pre-treat the solution to remove impurities before using it in the resin column.
• Store the resin in clean water or saturated saline/ethanol for long-term use.
