中文摘要	chemically modified electrodes prepared by treating the cobalt tetraphenylporphyrin modified glassy-carbon electrode at 750-degrees (hcme) are shown to catalyze the electrooxidation of hydrazine. the oxidation occurred at +0.63 v vs. ag/agcl (saturated potassium chloride) in ph 2.5 media. the catalytic response is evaluated with respect to solution ph, potential scan-rate, concentration dependence and flow-rate. the catalytic stability of the hcme is compared with that of the cobalt tetraphenylporphyrin adsorbed glassy-carbon electrode. the stability of the hcme was excellent in acidic solution and even in solutions containing organic solvent (50% ch3oh). when used as the sensing electrode in amperometric detection in flow-injection analysis, the hcme permitted sensitive detection of hydrazine at 0.5 v. the limit of detection was 0.1 ng. the linear range was from 50 ng to 2.4-mu-g. the method is very sensitive and selective.
