▎ 摘  要

NOVELTY - Adsorption resin comprises functional monomers and vinyl functionalized graphene oxide, crosslinking agent and initiator and which is obtained by polymerization reaction in porogen. The functional monomer includes acrylamide and 4-vinylbenzeneboronic acid. The crosslinking agent includes ethylene glycol dimethacrylate. USE - Adsorption resin for separation and purification of steviol glycosides (claimed). ADVANTAGE - The adsorption resin realizes selective reversible cyclic adsorption of steviol glycosides. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for using adsorption resin in separation and purification of steviol glycosides, which involves loading the adsorption resin into the chromatographic column, then passing steviol glycoside solution to be separated through chromatographic column, and eluting with eluent to obtain high-purity steviol glycoside.
