Disposable lithographically fabricated bismuth microelectrode arrays for stripping voltammetric detection of trace metals

摘要: Abstract This work reports the fabrication of disposable bismuth microdisk arrays by a thin-film microengineering approach and their utility in stripping analysis. The use bismuth, rather than mercury, as working electrode material results more environment-friendly electrochemical sensors. On other hand, configuration microelectrodes an array confers improved analytical performance compared to conventional macroelectrodes or single microelectrodes. Proof-of-principle applicability these devices was demonstrated for analysis Cd(II) Pb(II) using anodic voltammetry (ASV) Ni(II) adsorptive (AdSV) static solution.
