Abstract
In this paper, glucose oxidase (GOD) was immobilized in the course of sol-g el process of TEOS, and we cast the GOD-doped sol to different supports (si lica gel and molecular sieve) to prepare the GOD columns. It was demonstrat ed that the activity of GOD remained high in sol-gel matrix. With the appli cation of the GOD column prepared with sol-gel method to a flowing injectio n chemiluminescent system, glucose could be effectively determined with the linear range of the concentration in 3.5-70 mu mol/l and the detection Lim it was at 0.6 mu mol/l.
