    • Abstract

       

      Alternating and direct current polarograms of cadmium were recorded at different pH values in the range 1–12. At pH < 11, cadmium was reduced reversibly at the dropping mercury electrode, giving well-defined waves on both ac. and dc. polarography. The wave-width of ac. polarograms was less than that of dc. polarograms in the entire range of pH studied.
