Resin Pretreatment and Regeneration

Proper preparation and regeneration are critical to maximizing the performance of the Macroporous Adsorption Resin AB-8:

Pretreatment

To remove inert solvents and prepare the resin for use:

1. Soak the resin in ethanol (10–20 cm above the resin layer) for 3–4 hours.
2. Drain the soaking solution and repeat washing until the effluent is clear.
3. Rinse thoroughly with water until no ethanol smell remains.

Enhanced Regeneration

If the resin’s adsorption capacity declines or becomes contaminated:

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

Precautions for Use and Storage

To ensure optimal performance and longevity of the Macroporous Adsorption Resin AB-8, follow these guidelines:

• Storage Conditions: Maintain the resin at 5–40°C to prevent freezing or mold growth.
• Water Content Management: Avoid direct water injection if the resin dries out; instead, rehydrate it with ethanol before rinsing.
• Purification of Feedstock: Filter and clarify the solution before loading it onto the resin to prevent contamination.
• Long-Term Storage: Store the resin in clean water, saturated saline, or ethanol to prevent microbial growth.
