Studies on Catalytic Stripping Voltammetry of Trace Amount of Copper (Ⅱ) at an Electrode Chemically Modified with Oxine-Containing Carbon Paste

Abstract

Abstract: The oxine modified electrode was prepared on the basis of carbon paste and the process is rapid and simple. The catalytic stripping voltammetric characteristic of Cu(Ⅱ) on the modified electrode is studied and the method has been appiled to the determination of trace Cu (Ⅱ), and there is a good linear relationship between the concentration of Cu(Ⅱ) and peak height in the range of 1. 5×10^-9to 1. 5×10^-6mol/L for Cu(Ⅱ) we have detected the copper content in hair and blood with satisfactory results. Moreover, the reaction mechanism of the modified electrode is discussed and it is considered that the improvement of sensitivity and selection of the modified electrode is dependent on the complexing-absorbing property of electrode surface and a sensitive catalytic hydrogen wave produced.

Key words: Oxine, Carbon paste chemically modified electrode, Copper, Hair, Blood
