La resina di adsorbimento macroporosa AB-8 è un copolimero polare debole di tipo stirene (l'agente reticolante è il divinilbenzene, il monomero è l'acrilato di metile, il porogeno è il toluene, ecc.). È adatta per l'estrazione, la separazione e la purificazione di sostanze solubili in acqua e debolmente polari, come lo stevioside e gli alcaloidi.

Caratteristiche del prodotto:
Pretrattamento della resina
Tutte le resine di grado industriale contengono solventi inerti, quindi devono essere pretrattate in misura diversa a seconda delle esigenze applicative: nell'estrattore, aggiungere 10-20 cm di etanolo sopra lo strato di resina per immergerlo per 3-4 ore, quindi drenare la soluzione di ammollo. Per un processo di estrazione, utilizzare lo stesso metodo per lavare ripetutamente fino a quando l'uscita non riceve la soluzione di ammollo e aggiungere una quantità d'acqua 3 volte superiore alla provetta fino a quando non diventa torbida. Quindi risciacquare abbondantemente con acqua pulita fino a quando non si avverte più un odore evidente di etanolo, quindi può essere utilizzata per uso generale.
Rigenerazione migliorata:
Quando la resina viene utilizzata normalmente per un certo periodo, la capacità di adsorbimento si riduce o è fortemente inquinata, è necessario rafforzare il trattamento di rigenerazione. Il metodo consiste nell'aggiungere una soluzione di acido cloridrico al 3-5% a 10-20 cm sopra lo strato di resina e immergerla per 2-4 ore. La stessa soluzione di acido cloridrico, con una concentrazione pari a 5-7 volte il volume, viene risciacquata, quindi risciacquata abbondantemente con acqua pulita fino a quando il pH della soluzione di lavaggio in uscita non è neutro, quindi immersa in una soluzione di idrossido di sodio al 5% secondo il metodo sopra descritto per 2-4 ore, utilizzando lo stesso metodo. Risciacquare fino a quando non viene eliminata una quantità di soluzione di idrossido di sodio pari a 5-7 volte il volume, quindi risciacquare abbondantemente con acqua fino a quando il pH dell'effluente non è neutro, quindi può essere riutilizzata.
