A glucose electrode was constructed using a cobalt tetraphenyl porphyrin modified elec-trode with response time of less than 4s. A linearship was obtained between the current decrease and the glucose concentration in the range of 0.05-0.8mmol/L. The activity of the glucose oxidase kepr unchanged for 3 months in icebax condition. The selectivity was sati-sfactory.
