英文摘要	We employed a home-made tin-bismuth alloy electrode (SnBiE) as the working electrode with 1-(2-piridylazo)- 2-naphthol (PAN) as the complexing ligand to detect trace iron. This method is based on the cathodic reduction of Fe(III)-PAN complex to Fe(II)-PAN complex at the SnBiE by using adsorptive cathodic stripping voltammetry. The experimental parameters, such as the pH value, concentration of buffer solution, accumulation potential, accumulation time and the concentrations of PAN, were optimized, and the interference by other ions was investigated in detail. The response of Fe(III) was linear in the range of 1 nM to 900 nM with a detection limit of 0.2 nM (after 60 s of accumulation, s/n = 3). This method can also be applied to the determination of iron in coastal rivers and seawater with satisfactory results.
