Abstract
A prototype hand-held electroanalytical instrument has been developed for the simultaneous detection and determination of four electroactive ions in solution. The instrument, which can be battery powered, utili zes the technique of anodic linear-scan stripping voltammetry at a mer cury thin-film electrode. The instrumentation and its application to t he measurement of solution concentrations of cadmium, copper and lead in the range 10(-4)-10(-5) mol dm(-3) are described.
