Product Features and Advantages

The Macroporous Adsorption Resin AB-8 stands out due to its unique properties, which address common challenges in separation and purification processes:

1. Easy Observation: The milky white or light yellow color facilitates visual monitoring during the separation of colored organic compounds.
2. Chemical Stability: Insoluble in acids, alkalis, and organic solvents, allowing flexible selection of adsorbents and desorbents.
3. High Selectivity: Efficiently captures organic matter without interference from inorganic salts.
4. Easy Regeneration: Can be regenerated using water, dilute acids, alkalis, or low-boiling solvents like methanol or ethanol.
5. Durability: Strong mechanical strength ensures a long service life, reducing replacement costs.

Preparation and Regeneration

Resin Pretreatment

Before use, industrial-grade resins must undergo pretreatment to remove inert solvents:

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

Enhanced Regeneration

When adsorption capacity declines, follow these steps for regeneration:

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 solution, ensuring neutral pH after rinsing.
3. Thoroughly wash with water until the effluent is neutral.

Precautions for Use

• Store at 5–40°C to prevent freezing or mold growth.
• If the resin dries, restore it with ethanol before rinsing with water.
• Filter solutions before use to avoid resin contamination.
• Store washed resin in clean water or saturated saline/ethanol for long-term preservation.
