- Food and Beverage: To remove impurities and enhance the quality of natural sweeteners like stevioside.
- Environmental Protection: For water purification and the removal of organic pollutants.
- Chemical Industry: In the separation of complex mixtures and recovery of valuable solvents.
Its ability to operate under diverse conditions and its compatibility with various solvents make it a preferred choice for industrial-scale processes.
Pre-Treatment and Regeneration
Before use, the resin requires proper pretreatment to ensure optimal performance:
- Pretreatment: Soak the resin in ethanol (10–20 cm above the resin layer) for 3–4 hours, then rinse thoroughly with water until no ethanol smell remains.
- Enhanced Regeneration: For heavily contaminated resins, treat with 3–5% hydrochloric acid followed by 5% sodium hydroxide, ensuring complete neutralization of the effluent.
Proper maintenance extends the resin’s lifespan and maintains its adsorption efficiency.
Precautions for Safe Handling
- Store the resin at 5–40°C to prevent freezing or mold growth.
- Avoid direct water injection if the resin dries out; instead, rehydrate with ethanol before rinsing.
- Filter solutions before loading to prevent resin poisoning from impurities.
- Store the resin in clean water or saturated saline/ethanol for long-term use.
