Zinc in drinking water – Straightforward determination over a wide concentration range with the scTRACE Gold

Zinc is an essential trace element for humans. Excessive intake of zinc in higher concentrations can be harmful, however. There is no guideline value for zinc in the World Health Organization’s «Guidelines for Drinking-water Quality» because
typical levels usually found in drinking water are of no concern.

Anodic stripping voltammetry
is a viable, less sophisticated alternative to atomic absorption spectroscopy (AAS) for the determination of zinc in drinking water. While AAS (and competing methods) can only be performed in a laboratory,
anodic stripping voltammetric determinations can be used conventionally in the laboratory or alternatively in the field using with 946 Portable VA Analyzer. The determination is carried out on the scTRACE Gold electrode.
