What is Macroporous Adsorption Resin AB-8 used for?

AB-8 is widely used for the separation, purification, and concentration of natural products such as flavonoids, saponins, alkaloids, and antibiotics. It is especially effective in traditional Chinese medicine (TCM), plant extract purification, and pharmaceutical production.

How does AB-8 resin work in adsorption applications?

AB-8 functions through physical adsorption using its highly porous structure and large surface area. It selectively captures target molecules based on polarity, molecular size, and affinity, allowing for effective removal of impurities and enrichment of active compounds.

What are the key properties of AB-8 resin?

AB-8 features a macroporous, non-ionic, styrene-divinylbenzene copolymer structure. It has high mechanical strength, excellent chemical stability, large specific surface area, and good regeneration performance, making it suitable for repeated use in industrial processes.

How is AB-8 resin regenerated after use?

The resin can be regenerated using solvents such as ethanol, methanol, or other desorbing agents, depending on the adsorbed substances. After desorption, the resin should be rinsed thoroughly with water and, if necessary, reconditioned before reuse.

In which industries is AB-8 commonly applied?

AB-8 is widely used in the pharmaceutical, food, and beverage industries, especially for the purification of herbal extracts, functional ingredients, and biologically active compounds. It is also used in academic and industrial research.

Is AB-8 resin safe and compliant with industry standards?

Yes, AB-8 is manufactured in compliance with relevant safety and quality standards. It is non-toxic, non-polar, and chemically inert, making it suitable for use in food-grade and pharmaceutical-grade applications when properly handled and cleaned.

Produktegenskaper:

Färgen mjölkvit eller ljusgul gör bearbetningen bekvämare, och separationen och reningen av de färgade organiska föreningarna är lätt att observera.
De fysikaliska och kemiska egenskaperna är stabila och olösliga i alla syror, alkalier och organiska lösningsmedel, vilket är bekvämt för val av adsorbent och desorbent.
Den har god selektivitet för organiskt material och påverkas inte av närvaron av oorganiska salter.
Regenereringen är enkel. Regenereringsmedlet kan väljas bland vatten, utspädd alkali, utspädd syra eller lågkokande organiskt lösningsmedel. Såsom: metanol, etanol, aceton, etc.
God mekanisk hållfasthet och lång normal livslängd.

Förbehandling av harts

Industriella hartser innehåller alla inerta lösningsmedel, så de måste förbehandlas i olika grad beroende på tillämpningens behov: tillsätt 10–20 cm etanol ovanför hartslagret i extraktorn för att blötlägga i 3–4 timmar, och häll sedan ut blötläggningslösningen. För en extraktionsprocess, använd samma metod för att skölja upprepade gånger tills utloppet tar upp blötläggningslösningen och tillsätt 3 gånger så mycket vatten i provröret tills det inte längre är grumligt. Skölj sedan noggrant med rent vatten tills det inte finns någon uppenbar lukt av etanol, sedan kan det användas för allmänt bruk.

Förbättrad regenerering:

När hartset normalt används under en viss period, adsorptionskapaciteten minskar eller är akut förorenat, är det nödvändigt att förstärka regenereringsbehandlingen. Metoden är att tillsätta 3-5% saltsyralösning 10-20 cm ovanför hartslagret och blötlägga det i 2-4 timmar. Samma koncentration av 5-7 gånger volymen saltsyralösning sköljs och sedan sköljs noggrant med rent vatten tills pH-värdet i utloppstvättlösningen är neutralt. Sedan blötläggs det i 5% natriumhydroxidlösning enligt ovanstående metod i 2-4 timmar och samma metod används. Skölj tills 5-7 gånger volymen natriumhydroxidlösning passerar, skölj sedan noggrant med vatten tills pH-värdet i utloppsvattnet är neutralt, och sedan kan det tas i bruk igen.

Försiktighetsåtgärder

Hartset innehåller vatten och bör förvaras vid en temperatur på 5–40 °C under lagring och transport för att förhindra frysning vid låga temperaturer och mögel vid höga temperaturer, vilket påverkar dess användning.
Eftersom hartset utsätts för luft eller förlorar vatten av någon anledning, injicera inte vatten direkt för att förhindra att hartset flyter. Det kan impregneras med etanol för att återställa det till ett vått tillstånd och sedan rengöras med vatten.
Det adsorberade ämnet (lösningen) bör avlägsnas från föroreningar, filtreras och klargöras innan det placeras i kolonnen, för att så långt som möjligt undvika att föroreningar kommer in i hartskolonnen, för att inte orsaka akut hartsförgiftning och påverka användningen.
Hartset är avbrutet. Efter tvättning med vatten bör det förvaras i blötlagt rent vatten och bytas regelbundet för att förhindra kontaminering. Det kan också doppas i mättad saltlösning eller etanol för långtidsförvaring.
