| Title | Study of Xanthine Oxidase Immobilized Electrode Based on Modified Graphite  | ||
| Abstract | Xanthine oxidase (E . C. 1.2.3.2) was immobilized by adsorption on electrochem ically modi fied graphite plate to obtain an enzyme electrode. The current of the enzyme electrode in substrate (xanthine) solutions was found to be a result of the electrooxidation of H 20 2 gener ated in the enzyme layer. The linearity of the amperometric signal was up to a substrate concentration of 65 ^im at 0.6 V (vs. Ag/A gCl). The response time was 2 minutes. The enzyme electrode preserves 80% of its initial activity after perature. | ||
