Abstract: In this paper, dendritic Bi film electrodes with porous structure had successfully been prepared on glassy carbon electrode using a constant current electrolysis method based on hydrogen bubble dynamic templates.The electrode prepared using a large applied current density showed an increased internal electroactive area and a significantly improved electrochemical performance.The analytical utility of the prepared dendritic Bi film electrodes for the determination of Pb(Ⅱ) and Cd(Ⅱ) in the range of 5-50μg·L-1 were presented in combination with squarewave stripping voltammetry inmodel solution.Comparedwith non-porous Bi film electrode, the dendritic Bi film electrode exhibited higher sensitivity and lower detection limit.The prepared Bi film electrode with dendritic structure was also successfully applied to real water sample analysis.

Key words: Dendritic Bi film electrode, Electro-deposition, Hydrogen bubble dynamic template, Square wave stripping analysis, Pb(Ⅱ) and Cd(Ⅱ)
