The gallium-modified bismuth film electrode (GaBFE) has been shown to be an excellent alternative to the mercury film electrode for anodic stripping voltammetric (ASV) analysis of a number of metals, including copper. However, in the presence of as little as 20 mM chloride, the benefit of the BFE disappears making the electrochemical analysis of copper in samples of high ionic strength, such as seawater, difficult. We present the preparation of a solid-phase extraction (SPE) medium consisting of Ambersorb XAD-4 resin impregnated with 1-(2-pyridylazo)-2-naphthol (PAN) and the results for the ASV analysis of copper, cadmium, and lead extracted from deionized and synthetic seawater samples after isolation using the extractor. The extractor was used to prepare seawater samples collected from Marina Del Rey Harbor, California, as part of a marine water quality survey.
