Pretreatment and Regeneration Process
Proper pretreatment and regeneration are critical to maintaining the performance of the AB-8 resin. Here’s a step-by-step guide:
Pretreatment
- Soak the resin in 10–20 cm of ethanol for 3–4 hours.
- Drain the soaking solution and repeat washing until the effluent is clear.
- Rinse with clean water until no ethanol smell remains.
Enhanced Regeneration
- Soak the resin in 3–5% hydrochloric acid for 2–4 hours.
- Rinse with water until the pH is neutral.
- Repeat the process with 5% sodium hydroxide solution.
- Thoroughly rinse with water to ensure neutrality before reuse.
For detailed instructions, refer to the product manual.
Precautions for Use
- Store the resin at 5–40°C to prevent freezing or mildew.
- Avoid direct water injection if the resin dries out; use ethanol to rehydrate it first.
- Ensure the solution is filtered and clarified before passing it through the resin to prevent contamination.
- Store the resin in clean water or ethanol when not in use to maintain its performance.
