Determination of Zn(II) in undisturbed samples using the bismuth electrode

The journal Analytical Methods has just published our paper about the use of the bismuth bulk rotating disk electrode (BiB-RDE) as a new and advantageous alternative to determine heavy metal ions in undisturbed environmental and biological samples (pH 7.5) by anodic stripping voltammetry, with demonstrated applicability to the determination of Zn(II) in rainwater, tap water and urine. The proposed method benefits from the insensitiveness of the bismuth bulk electrode to the Bi(III) hydrolysis that affects the common “in situ” Bi film approach preventing its use at intermediate to alkaline pH.
