• Food Industry: Removal of impurities and coloring agents from food products, ensuring compliance with quality standards.
• Environmental Protection: Water purification and removal of organic pollutants from industrial wastewater.
• Chemical Processing: Separation of weakly polar substances from aqueous solutions, enhancing product purity.

Product Pretreatment and Regeneration

Before use, the resin requires preliminary treatment to remove residual solvents and ensure optimal performance:

• Pretreatment: Soak the resin in ethanol (10–20 cm above the resin layer) for 3–4 hours, then rinse with water until no ethanol odor remains.
• Enhanced Regeneration: For heavily contaminated resins, treat with 3–5% hydrochloric acid followed by 5% sodium hydroxide, ensuring thorough rinsing to neutralize pH levels.

Storage and Handling Precautions

• Store the resin at 5–40°C to prevent freezing or mold growth.
• Avoid direct water contact if the resin dries out; instead, rehydrate with ethanol before cleaning.
• Ensure pre-filtration of feed solutions to prevent resin contamination and poisoning.
• Store the resin in clean water, saline, or ethanol when not in use to maintain its integrity.
