Preparation and Regeneration Guidelines

Proper handling of the Macroporous Adsorption Resin AB-8 ensures optimal performance. Here are the key steps:

Resin Pretreatment

1. Soak the resin in 10–20 cm of ethanol for 3–4 hours, then drain the solution. Repeat washing until the effluent is clear. Rinse with water until no ethanol smell remains.

Enhanced Regeneration

1. Treat with 3–5% hydrochloric acid for 2–4 hours, followed by rinsing with water until neutral pH. 2. Soak in 5% sodium hydroxide solution for 2–4 hours, then rinse thoroughly with water.

Storage and Handling Precautions

• Store at 5–40°C to prevent freezing or mold growth.
• Avoid direct water injection if the resin dries out; instead, use ethanol to rehydrate it.
• Filter solutions before use to prevent resin contamination.
• Store in clean water or saturated saline/ethanol for long-term preservation.
