- Environmental Protection: For removing heavy metals and organic pollutants from wastewater, contributing to sustainable environmental management.
Preparation, Regeneration, and Storage
Proper handling of the Macroporous Adsorption Resin AB-8 is critical to maintaining its performance:
Pre-Treatment
Before use, the resin must be pretreated to remove inert solvents. This involves soaking the resin in ethanol for 3–4 hours, followed by thorough rinsing with water until no ethanol odor remains. This process ensures the resin is ready for general applications.
Enhanced Regeneration
When the resin’s adsorption capacity diminishes or becomes contaminated, it can be regenerated using the following steps:
- Soak the resin in 3–5% hydrochloric acid for 2–4 hours, then rinse with 5–7 times its volume of the same solution.
- Follow with a 5% sodium hydroxide soak for 2–4 hours, followed by thorough rinsing with water until neutrality is achieved.
This regeneration process restores the resin’s performance, ensuring long-term cost-effectiveness.
Storage and Handling
To maintain the resin’s stability, it should be stored at 5–40°C, avoiding freezing or high-temperature environments. If the resin dries out, it can be rehydrated by soaking in ethanol before rinsing with water.
