Bismuth Film-Coated Gold Ultramicroelectrode Array for Simultaneous Quantification of Pb(II) and Cd(II) by Square Wave Anodic Stripping Voltammetry

This paper optimizes a bismuth film on a gold ultramicroelectrode array for simultaneous lead and cadmium measurement in water by square-wave anodic stripping voltammetry. Bismuth is the electrode film, chosen by the authors for lower toxicity than mercury.

Key numbers

This paper reports no numerical findings relevant to bismuth exposure.

Methods (brief)

Operating parameters were optimized with a Box-Behnken design. Reported detection limits were 5 µg/L for lead and 7 µg/L for cadmium (abstract).

Evidence fitness

This is a materials or analytical chemistry paper in which bismuth is a component of an engineered material. It does not support dietary exposure or toxicity claims for bismuth, and no bismuth was measured in food, water, feed, soil or human or animal tissue.

Limitations

Lead and cadmium results are outside the scope of this page.
