Macroporous Adsorption Resin AB-8 is a high-performance, industrial-grade separation medium engineered for the precise purification of organic compounds. Featuring a sophisticated macroporous structure and a large specific surface area, AB-8 excels in removing pigments, flavors, and organic contaminants from complex liquid streams. It is an indispensable tool for industries requiring high-purity product streams, ensuring consistent quality and regulatory compliance across pharmaceutical, food, and environmental sectors.
Developed by Hebei Lijiang Biotechnology Co., Ltd., AB-8 is designed for maximum durability and efficiency. Its unique chemical stability makes it insoluble in acids, alkalis, and most organic solvents, allowing for flexible regeneration and long-term operational life. Whether integrated into large-scale industrial columns or high-precision laboratory chromatography systems, AB-8 provides superior adsorption kinetics and exceptional selectivity for organic matter, significantly reducing operational costs while enhancing product purity.

Industrial grade resins contain inert solvents. Pretreatment involves soaking the resin in ethanol for 3-4 hours, followed by repeated washing until the solution is clear, and a final rinse with clean water until the ethanol smell is gone.
Depending on the adsorbed substance, regeneration agents can include water, dilute alkali, dilute acid, or low-boiling organic solvents such as methanol, ethanol, and acetone.
To avoid acute resin poisoning, the solution to be adsorbed should undergo impurity removal, filtration, and clarification before being loaded onto the resin column.
Resins should be stored at temperatures between 5-40ºC to prevent freezing or mildew. For long-term storage, they should be immersed in clean water (changed regularly), saturated saline, or ethanol.
Yes, AB-8 is widely used in pharmaceutical manufacturing for the effective separation of active pharmaceutical ingredients (APIs) from impurities, enhancing overall product safety.
When adsorption capacity reduces due to acute pollution, enhanced regeneration involves sequential soaking in 3-5% hydrochloric acid and 5% sodium hydroxide solutions, followed by neutral water rinsing.
