When Wang's research group introduced a new type of a working electrode: bismuth film plated electrode (BiFE), it has started attracting increasing attention in the field of electrochemical stripping analysis. These electrodes are shown to be very attractive alternative to common mercury-based electrodes, which are predominantly used in analysis of trace heavy metals.For the determination of heavy metals (Zn, Cd, Pb, Cu) used square wave anodic stripping voltammetry on a bismuth film coated glassy carbon electrode. Using the conditions selected for the simultaneous determination of the metals stated, the limits of detection were 0.47 µg/dm3, 0.1 µg/dm3, 0.12 µg/dm3 and 0.9 µg/dm3 for Zn, Cd, Pb and Cu, respectively, and the relative standard deviations were 12.6 %, 8.75 %, 5.68 % and 39.5 % at the 20 µg/dm3 level for Zn, Cd, Pb and Cu, respectively (n=5).
