Company Background
Hebei Lijiang Biotechnology Co., Ltd. is a leading manufacturer specializing in advanced materials for separation and purification. With a focus on innovation and quality, the company has established itself as a trusted provider of macroporous adsorption resins and related technologies. Their commitment to research and development ensures that their products meet the evolving needs of industries worldwide.
Preparation and Maintenance
Proper preparation and maintenance are critical to maximizing the performance of the Macroporous Adsorption Resin AB-8. Key steps include:
Resin Pretreatment
Industrial-grade resins require pretreatment to remove inert solvents. The process involves soaking the resin in ethanol (10–20 cm above the resin layer) for 3–4 hours, followed by thorough washing with water until the effluent is clear. This ensures the resin is ready for extraction processes.
Enhanced Regeneration
When the resin’s adsorption capacity decreases, enhanced regeneration is necessary. This involves soaking the resin in 3–5% hydrochloric acid for 2–4 hours, rinsing with water until neutral, and then repeating the process with 5% sodium hydroxide. This restores the resin’s efficiency and extends its lifespan.
Precautions
- Store the resin at 5–40°C to prevent freezing or mildew.
- Avoid direct water injection if the resin dries out; instead, use ethanol to rehydrate it before cleaning.
- Filter solutions before use to prevent resin contamination and poisoning.
- Keep the resin submerged in clean water or saturated saline/ethanol during storage to maintain its integrity.
