Preparation and Regeneration

Proper preparation and regeneration are essential to maintain the resin’s performance:

Resin Pretreatment

Industrial-grade resins often contain inert solvents. To prepare the resin for use:

1. Add 10–20 cm of ethanol above the resin layer and soak for 3–4 hours.
2. Drain the soaking solution and repeat the washing process until the effluent is clear.
3. Rinse with clean water until there is no noticeable ethanol smell.

Enhanced Regeneration

When the resin’s adsorption capacity decreases or it becomes contaminated:

1. Soak the resin in 3–5% hydrochloric acid for 2–4 hours.
2. Rinse with 5–7 times the volume of hydrochloric acid solution until the pH is neutral.
3. Repeat the process with 5% sodium hydroxide solution, followed by thorough rinsing with water.

Precautions

To ensure optimal performance and longevity of the resin:

• Store the resin at 5–40°C to prevent freezing or mold growth.
• If the resin dries out, avoid direct water contact. Instead, rehydrate it with ethanol before rinsing with water.
• Pre-treat solutions by removing impurities and filtering them before use to prevent resin contamination.
• Store the resin in clean water or saturated saline/ethanol when not in use to prevent microbial growth.
