Abstract: In this paper,α-amylase,glucoamylase and glucose oxidase were Immobilized by sol-gel.With its application to jlowing injection chemilumine-scence system,starch could be rapidly determined with the liner rage of its concentration in 10-200mg/L and detection limit at 0.2mg/L.The relativte standard deviation (RSD) is 1.8% with 10 continuous assays.

Key words: Sol-gel technique Immobilized Enzyme Chemiluminescence Starch
