文摘

Bismuth film microelectrodes have a potential to replace toxic mercury used most frequently for determination of heavy metals by anodic stripping voltammetry. We developed diamond-like carbon microelectrodes doped by nitrogen as a support for bismuth electroplating. Bismuth-plated as well as bare microelectrode arrays were used for lead determination in aqueous solutions. The influence of many parameters on responses was investigated.
