Preparation and Maintenance

To ensure optimal performance, proper preparation and maintenance of the Macroporous Adsorption Resin AB-8 are essential. Here are the recommended steps:

Resin Pretreatment

Industrial-grade resins often contain inert solvents, necessitating pretreatment. The process involves:

1. Soaking the resin in ethanol (10–20 cm above the resin layer) for 3–4 hours.
2. Draining the solution and repeating the washing process until the effluent is clear.
3. Rinsing with clean water until the ethanol odor is eliminated.

Enhanced Regeneration

When the resin's adsorption capacity diminishes, enhanced regeneration is required:

1. Soak the resin in 3–5% hydrochloric acid for 2–4 hours, followed by rinsing with water until neutral pH is achieved.
2. Subsequently, soak the resin in 5% sodium hydroxide solution for 2–4 hours and rinse thoroughly with water.

Precautions

• Store the resin at 5–40°C to prevent freezing or mold growth.
• Avoid direct water injection if the resin dries out; instead, rehydrate it with ethanol before rinsing.
• Ensure feed solutions are filtered and clarified before use to prevent resin contamination.
• Store the resin in clean water or saturated saline/ethanol when not in use.
