Resin Pretreatment and Regeneration
Proper pretreatment and regeneration are essential to maintain the resin’s performance. For industrial-grade resins, the following steps are recommended:
Pretreatment
1. Soak the resin in 10–20 cm of ethanol for 3–4 hours. Drain the solution and repeat the washing process until the effluent is clear. 2. Rinse thoroughly with clean water until no ethanol odor remains. This prepares the resin for general use.
Enhanced Regeneration
1. Soak the resin in 3–5% hydrochloric acid for 2–4 hours, followed by rinsing with 5–7 times the volume of the acid solution. 2. Repeat the process with 5% sodium hydroxide solution, ensuring the effluent pH is neutral. This restores the resin’s adsorption capacity and extends its lifespan.
Precautions for Storage and Use
- Storage Conditions: Maintain the resin at 5–40°C to prevent freezing or mold growth. Avoid direct exposure to air or dehydration, which can compromise its integrity.
- Rehydration: If the resin dries out, rehydrate it using ethanol before rinsing with water to avoid floating issues.
- Pre-Filtration: Ensure the feed solution is filtered and clarified to prevent impurities from clogging the resin column and causing acute poisoning.
- Long-Term Storage: Store the resin in clean water, saturated saline, or ethanol to maintain its performance over time.
