Pretreatment and Regeneration Procedures
To ensure optimal performance, the resin must be properly pretreated and regenerated. The steps are as follows:
Pretreatment
- Soak the resin in ethanol (10–20 cm above the resin layer) for 3–4 hours.
- Drain the soaking solution and repeat the washing process 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.
- Soak in 5% sodium hydroxide for 2–4 hours, then rinse thoroughly.

Precautions for Storage and Usage
- Store the resin at 5–40°C to prevent freezing or mildew.
- If the resin dries out, restore it with ethanol before rinsing with water.
- Filter solutions before use to avoid resin poisoning from impurities.
- Store the resin in clean water or saturated saline/ethanol when not in use.
