Chemical Industry: Used in the separation of weakly polar substances, facilitating the production of high-value chemicals.

Proper Handling and Maintenance

To ensure optimal performance, proper handling and maintenance of the Macroporous Adsorption Resin AB-8 are essential. Here are some guidelines:

Resin Pretreatment

Before use, the resin must be pretreated to remove inert solvents. The process involves:

Soaking the resin in ethanol for 3-4 hours, followed by draining the solution.
Repeating the washing process until the outlet solution is clear, then rinsing with water until no ethanol odor remains.

Enhanced Regeneration

If the resin's adsorption capacity decreases, enhanced regeneration is required:

Soak the resin in a 3-5% hydrochloric acid solution for 2-4 hours, then rinse with water until neutral pH.
Follow with a 5% sodium hydroxide solution treatment, again rinsing until neutral pH is achieved.

Precautions

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.
Ensure the solution to be adsorbed is filtered and clarified to prevent resin poisoning.
Store the resin in clean water or saturated saline/ethanol when not in use.
