Adsorptive stripping voltammetry (AdSV) was successfully explored for the determination of aluminum(III) in sodium carbonate solution (1 M) on a preplated bismuth film electrode (BiFE). Microscopic investigation displays that the morphology of the preplated bismuth film on Pt electrode relates to the plating conditions. The resulted perfect dendritic polycrystalline BiFE demonstrates better performance than the flake single crystal BiFE in AdSV determination of Al(III) in the presence of Eriochrome blue black R (EBBR). Under the selected conditions, the limit of detection( 3σ ) for Al(III) on flake and dendrite BiFE are 1.02×10 −8 M and 5.6×10 −10 M, respectively, and the current variation ratio of the coexistent ions(Ca II , V V , Si IV , Mg II , Fe II and Fe III ) is less than ±0.700 % in all cases.
