Determination of sodium cyclamate was studied by the polarographic method. Sodium cyclamate was decomposed by heating with AcOH and NaNO2, and sulfuric ions liberated from sodium cyclamate were completely precipitated as PbSO4 in 50% EtOH solution by the addition of excess of Pb(AcO)2. The precipitate of PbSO4 was filtered and surplus Pb ions were measured by polarography in the electrolytic solution of 45% EtOH with 0.04N NH4CNS and 0.01N HCl as a supporting electrolyte, and Triton X-100 as a maximum suppressor. The amount of sodium cyclamate was inversely proportional to the wave height of Pb ions and, therefore, sodium cyclamate of 0.2∼9 mg./ml., particularly even 2.5 μg., could be easily determined indirectly. This method was not interfered by glucose, lactose, sucrose, starch, saccharin sodium, or dulcin. Consequently, this method is thought to be a very convenient and accurate way for the determination of sodium cyclamate, especially in artificial sweetening preparations.
