AB-8 is employed in the removal of heavy metals and organic contaminants from wastewater. Its robust mechanical strength ensures long-term use in harsh environmental conditions.
Product Pretreatment and Regeneration
To ensure optimal performance, proper pretreatment and regeneration of the Macroporous Adsorption Resin AB-8 are essential. Here’s a step-by-step guide:
Pretreatment
- Soak the resin in 10–20 cm of ethanol for 3–4 hours.
- Drain the soaking solution and repeat washing with ethanol until the effluent is clear.
- Rinse with clean water until no ethanol smell remains.
Enhanced Regeneration
- Soak the resin in 3–5% hydrochloric acid for 2–4 hours, then rinse with 5–7 times the volume of the solution.
- Repeat the process with 5% sodium hydroxide solution, ensuring the effluent pH is neutral after rinsing.
Precautions for Storage and Handling
- Store the resin at 5–40°C to prevent freezing or microbial growth.
- Avoid direct water contact if the resin dries out; instead, rehydrate it with ethanol before cleaning.
- Filter solutions before use to prevent resin poisoning from impurities.
- Store the resin in clean water or saturated saline/ethanol for long-term preservation.
