Applications

The versatility of Macroporous Adsorption Resin AB-8 makes it suitable for a variety of applications:

• Pharmaceuticals: Extraction and purification of alkaloids, glycosides (e.g., stevioside), and other bioactive compounds.
• Food Industry: Removal of impurities and pigments from natural extracts, such as herbal teas and fruit juices.
• Environmental Protection: Treatment of wastewater to remove organic pollutants and heavy metals.
• Chemical Manufacturing: Separation of organic compounds from complex mixtures in industrial processes.

Pretreatment and Regeneration

Proper pretreatment ensures optimal performance of the resin. Before use, the resin should be soaked in ethanol (10–20 cm above the resin layer) for 3–4 hours, followed by thorough washing with water until no ethanol smell remains. For enhanced regeneration, the resin can be treated with 3–5% hydrochloric acid, rinsed, and then exposed to 5% sodium hydroxide solution. This process restores its adsorption capacity and extends its service life.

Storage and Handling Precautions

1. Store at 5–40°C to prevent freezing or mold growth.
2. If the resin dries out, rehydrate it with ethanol before washing with water.
3. Filter solutions before loading onto the resin to avoid contamination.
4. Keep the resin submerged in water or saturated saline/ethanol during storage to prevent degradation.
