The purpose of this investigation was to find a rapid, sensitive, and reliable method for detecting toxic inorganic materials in water in time of emergency, when contamination was suspected. The method had to be sensitive at the toxic level of the contaminant so that it could be used as a warning alarm. The classical polarographic method appears to satisfy these requirements. This method involves electrolysis at controlled (but variable) potential at a dropping mercury electrode.
