Its stability in aqueous environments and ease of regeneration make it suitable for both industrial and municipal water treatment systems. 3. Food and Beverage Processing The resin is used to decolorize and purify sugar syrups, fruit juices, and other food products. Its ability to handle large volumes without compromising quality is a significant advantage in this sector. 4. Environmental Remediation 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. About Hebei Lijiang Biotechnology Co., Ltd.
