Abstract
An oxine modified electrode is prepared on the basis of carbon paste. The process is rapid and simple. The catalytic stripping voltammetric characteristic of Cu(II) on the modified electrode was studied and the method has been applied to the determination of trace Cu(II), and there was good linear relationship between the concentration of Cu(II) and the peak height in the concentration range of 1.5 x 10(-)-1.5 x 10(-6) mol/L for Cu(II). We have detected the copper content of human hair and blood with satisfactory results. Moreover, the reaction mechanism of the modified electrode was discussed. It was found that the improvement of sensitivity and selection of the modified electrode was dependent of the complex adsorbing property of the electrode surface and the sensitive catalytic hydrogen wave produce.
