Preparation and Regeneration

Proper handling ensures optimal performance:

Pre-Treatment

1. Soak the resin in ethanol (10–20 cm above the resin layer) for 3–4 hours. Drain the solution and repeat until the effluent is clear.

2. Rinse with clean water until no ethanol smell remains.

Enhanced Regeneration

1. Soak in 3–5% hydrochloric acid for 2–4 hours. Rinse with 5–7 times the resin volume of HCl solution.

2. Neutralize with 5% sodium hydroxide for 2–4 hours, followed by thorough water rinsing until neutral pH is achieved.

Storage and Handling Precautions

1. Store at 5–40°C to prevent freezing or mold growth.
2. If the resin dries, restore it with ethanol before rinsing with water.
3. Filter solutions before loading to avoid resin contamination.
4. Store in clean water or saturated saline/ethanol for long-term preservation.
