| 中文摘要 | a multi-cylinder microelectrode coupled with a conventional glassy carbon disc electrode (mcm/gc) was prepared and characterized using cyclic voltammetry and chronoamperometry. it was demonstrated that in the same way as one observed a steady-state current at closely spaced microelectrodes when redox recycling takes place, the same effect can be obtained with the mcm/gc device. the experimental results obtained with k3fe(cn)6 solutions were compared with a previously developed theory. further, it was demonstrated that with a carbon fibre mcm/gc device, the voltammetric behaviour of dopamine is greatly improved by virtue of redox recycling, hence giving high sensitivity. the steady-state collection current was linearly related to dopamine concentration in the range 1 x 10(-4) to 5 x 10(-7) mol l-1, and the detection limit was 2 x 10(-7) mol l-1. the influence of coexisting ascorbic acid was also investigated. this device was applied successfully in the determination of dopamine hydrochloride in pharmaceutical preparations. |
