| 英文摘要 | An anodic stripping analysis system based on two-step prepared bismuth electrode for on-line determination of lead (Pb2+) in tap water samples is presented here. Such two-step prepared electrode modified in-situ and ex-situ bismuth film shows remarkably improved sensitivity to Pb2+ in acidic solution (pH <= 2). The designed electrode has been successfully used for determination of Pb2+ in acidic solution by anodic stripping voltammetry with a linear range of 1.3-20 mu gL(-1). The sensitivity and detection limit are 19 nAL mu g(-1) and 0.8 mu gL(-1), respectively. The practical application of the proposed electrode has been carried out for the on-line determination of trace levels of Pb2+ in real tap water samples.; An anodic stripping analysis system based on two-step prepared bismuth electrode for on-line determination of lead (Pb(2+)) in tap water samples is presented here.
