Abstract: The adsorption and desorption behaviour of macroporous adsorbent AB-8 for stevioside were investigated. The effects of pH, eluents and flow rate on the adsorption and desorption properties were studied. The results show that the adsorbent Ab-8 has a high adsorption capacity for stevioside and the elution is easy.

Key words: styrene-divinylbeiizene-methylacrylate copolymer, adsorption resin, stevioside
