โฆ Synopsis
The enzyme glucose oxidase (GO) was covalently Cg.oCg,, immobilized onto a poly(vinyl alcohol) hydrogel, cross-linked with glutardialdehyde and a polyazonium salt. To compare the kinetic parameters of immobilized GO with the known kinetic cg, A Cg, B parameters of soluble GO, the diffusion cell method was used.
Between two compartments, containing solutions with
CGo
different glucose concentrations, a GO-containing hydrogel D~ff membrane was placed. Simultaneous diffusion through and

Models of membrane systems containing immobilized glucose oxidase and catalase operating together or in- dependently have been developed. A rotated disk electrode apparatus was employed with novel electrochemical operating conditions to experimentally determine mass transfer and intrinsic kinetic pa
During the continuing rapid daelopment of analytical methods based on immobilized enzymes, several techniques have been described for the determination of glucose. For example, glucose oxidase (E.C.1.1.3.4) entrapped in polyacrylamide gel was used by Updike and Hicks in two methods. In one case [l]
