Pretreatment and Regeneration Procedures

Pretreatment

Before use, the resin must be pretreated to remove inert solvents. This involves soaking in ethanol, followed by thorough rinsing with water until no ethanol odor remains. This process ensures optimal performance and prevents contamination (NIST).

Enhanced Regeneration

When the resin’s adsorption capacity declines, it can be regenerated using 3–5% hydrochloric acid and 5% sodium hydroxide solutions. This process restores the resin’s functionality, extending its service life.

Precautions for Use and Storage

• Store the resin 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 loading onto the resin to prevent impurity buildup.
• Keep the resin submerged in water or ethanol during storage to maintain its integrity.
