Product Overview

Macroporous Adsorption Resin AB-8 is a styrene-type weakly polar copolymer, synthesized using divinylbenzene as a crosslinking agent, methyl acrylate as a monomer, and toluene as a porogen. This unique composition ensures the resin's stability and effectiveness in diverse environments. Its primary function is to adsorb and separate organic compounds from aqueous solutions, making it ideal for applications in pharmaceuticals, food processing, and environmental protection. The resin's macroporous structure allows for efficient mass transfer, while its weak polarity enables selective adsorption of target molecules.

Preparation and Regeneration

Proper preparation and regeneration are critical to maximizing the performance of AB-8 resin. Here are the recommended procedures:

Resin Pretreatment

1. Soak the resin in 10–20 cm of ethanol for 3–4 hours. Drain the solution and repeat washing until the effluent is clear. 2. Rinse with clean water until no ethanol odor remains. This ensures the resin is ready for general use.

Enhanced Regeneration

1. Soak the resin in 3–5% hydrochloric acid for 2–4 hours. Rinse with 5–7 times the volume of the acid solution until neutral. 2. Soak in 5% sodium hydroxide for 2–4 hours, then rinse with 5–7 times the volume of the base solution. 3. Final rinse with water until the pH of the effluent is neutral. This restores the resin's adsorption capacity for repeated use.

For detailed instructions, refer to the product documentation.

Precautions for Storage and Handling

To maintain the resin's performance, follow these guidelines:

1. Store at 5–40°C to prevent freezing or mildew. Avoid exposure to extreme temperatures.
2. If the resin dries out, immerse it in ethanol to rehydrate before washing with water. Direct water addition may cause floating.
3. Ensure feed solutions are filtered and clarified before use to prevent resin fouling.
4. Store the resin in clean water or saturated saline/ethanol when not in use to prevent contamination.
