Enhanced Regeneration and Maintenance

To maintain optimal performance, the resin requires periodic regeneration. The process involves:

1. Soaking the resin in 10–20 cm of ethanol for 3–4 hours, followed by thorough rinsing with water until no ethanol odor remains.
2. For enhanced regeneration, treating the resin with 3–5% hydrochloric acid or 5% sodium hydroxide solutions, followed by neutralization with water.

Proper storage is critical. The resin should be kept at 5–40°C, avoiding freezing or high-temperature exposure. If the resin dries out, it can be rehydrated using ethanol before rinsing with water. For long-term storage, soaking in saturated saline or ethanol is recommended.
