Applications

The Macroporous Adsorption Resin AB-8 is widely used in various industries due to its adaptability and performance. Key applications include:

• Pharmaceuticals: Extraction and purification of alkaloids, glycosides, and other bioactive compounds.
• Food and Beverage: Removal of impurities and colorants from natural extracts, such as stevioside from Stevia leaves.
• Environmental Protection: Treatment of wastewater to remove organic pollutants and heavy metals.
• Chemical Industry: Separation of weakly polar substances from complex mixtures.

Its versatility is further enhanced by its compatibility with anion chromatography resin and water purification resin systems, making it a preferred choice for multi-step purification processes.

Preparation and Regeneration

Proper preparation and regeneration are critical to maintaining the performance of Macroporous Adsorption Resin AB-8. The resin requires pretreatment to remove inert solvents:

1. Soak the resin in 10–20 cm of ethanol for 3–4 hours, then drain the solution.
2. Repeat washing with ethanol until the effluent is clear, followed by thorough rinsing with water until no ethanol odor remains.

For enhanced regeneration after prolonged use:

1. Soak in 3–5% hydrochloric acid for 2–4 hours, then rinse with 5–7 times the volume of the solution.
2. Repeat the process with 5% sodium hydroxide, ensuring the pH of the effluent is neutral before reuse.

These steps ensure the resin retains its adsorption capacity and mechanical integrity over time.

Precautions and Storage

To maximize the lifespan of Macroporous Adsorption Resin AB-8, follow these guidelines:

• Store at 5–40°C to prevent freezing or microbial growth.
• Avoid direct water injection if the resin dries out; instead, rehydrate with ethanol before rinsing.
• Filter solutions before loading to prevent resin poisoning from impurities.
• Keep the resin submerged in clean water or saturated saline/ethanol when not in use.

Adhering to these precautions ensures consistent performance and minimizes operational disruptions.
