| 中文摘要 | a sensitive electrochemical detection scheme for morphine has been proposed by utilizing the ordered mesoporous carbon modified glassy carbon electrode (omc/gce). the electrochemical behaviour of morphine at the omc/gce was investigated by cyclic voltammetry. the modified electrode displayed a decrease in the overpotential (ca. 82 mv) and an obvious increase in the peak current (80 times) compared to the bare glassy carbon electrode (gce). the results indicated that omc/gce remarkably enhanced electrocatalytic activity towards the oxidation of morphine. linear response was found over the range from 0.1 mu m to 20 mu m with a high sensitivity of 1.74 mu a/mu m and low detection limit of 10 nm (s/n = 3). and the relative standard deviation was 0.86% (n = 5). moreover, combining with a medium-exchange procedure, the omc/gce has also been successfully applied to the selective determination of morphine in urine samples with a low detection limit of 50 nm and satisfied recovery of 96.4%. the good results indicate that the cmc/gce holds great promise in practical application.
