Preparation and Regeneration of AB-8 Resin
Proper preparation and regeneration of AB-8 resin are essential to maintain its performance and longevity. Here are the recommended procedures:
Resin Pretreatment
Industrial-grade resins often contain inert solvents, requiring pretreatment before use. Follow these steps:
- Add 10–20 cm of ethanol above the resin layer in the extractor and soak for 3–4 hours.
- Drain the soaking solution and repeat the washing process with ethanol until the effluent is clear.
- Rinse with clean water until there is no noticeable ethanol smell, ensuring the resin is ready for general use.
Enhanced Regeneration
If the resin’s adsorption capacity decreases or it becomes contaminated, perform the following regeneration steps:
- Soak the resin in 3–5% hydrochloric acid solution for 2–4 hours, then rinse with 5–7 times the volume of the solution.
- Rinse with water until the pH of the effluent is neutral.
- Repeat the process with 5% sodium hydroxide solution, ensuring thorough rinsing to restore the resin’s functionality.
Precautions for Handling AB-8 Resin
To ensure optimal performance and safety, follow these precautions:
- Storage Conditions: Maintain the resin at a temperature of 5–40°C to prevent freezing or mildew. Avoid exposure to extreme temperatures during transportation.
- Rehydration: If the resin loses water, avoid direct water injection. Instead, rehydrate it with ethanol and then rinse with water to restore its wet state.
- Purification Before Use: Filter and clarify the solution before introducing it to the resin column to prevent impurities from causing acute resin poisoning.
- Storage After Use: After washing with water, store the resin in clean water or immerse it in saturated saline or ethanol for long-term preservation.
Why Choose AB-8 Resin?
