- Food and Beverage: AB-8 aids in the separation of natural products like stevioside, enhancing the quality of food additives and sweeteners.
- Environmental Protection: The resin plays a role in treating industrial effluents, reducing the environmental impact of chemical processes.
Preparation and Regeneration Procedures
To ensure optimal performance, AB-8 resin requires proper pretreatment and periodic regeneration. The following steps outline the process:
Pretreatment
Industrial-grade resins often contain inert solvents. To prepare AB-8 for use:
- 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 until the outlet solution is clear.
- Rinse with clean water until no ethanol odor remains.
Enhanced Regeneration
When the resin’s adsorption capacity diminishes:
- Soak the resin in 3–5% hydrochloric acid for 2–4 hours, then rinse with 5–7 times the volume of the solution.
- Repeat the process with 5% sodium hydroxide solution, ensuring the effluent pH is neutral.
- Rinse thoroughly with water before reuse.
Precautions for Storage and Handling
To maintain the integrity of AB-8 resin, adhere to the following guidelines:
- Store the resin at 5–40°C to prevent freezing or mold growth.
- If the resin dries out, rehydrate it with ethanol before rinsing with water to avoid floating.
- Ensure the feed solution is filtered and clarified before column loading to prevent contamination.
- Store the resin in clean water or saturated saline/ethanol for long-term use.
