A controlled‐potential coulometric determination of lead, cadmium, and zinc in glasses is reported. The method consists of reducing or oxidizing the various ions at appropriate potentials. The integrated current resulting from the electrolysis is used to calculate the amount of substance present. The lower limit of detection, without background corrections, is approximately 0.2 millifaradays for each ion. The method is accurate and more rapid than the usual classical methods of analysis.
