摘要：

A method for the determination of saccharin in soft drinks, tonic waters, fruit juices and sweeteners by differential pulse polarography is reported. Saccharin is reduced at a dropping mercury electrode. The best determination is performed at pH 1 (detection limit: 0.5 ppm) or at pH 8.5 (detection limit: 1 ppm). In order to elucidate the mechanism of the electrode processes the reaction products were produced by electrolysis at controlled potential. The proceeding of the electrolysis was controlled by HPLC with UV-detection. The isolated products were identified by IR- and NMR-spectroscopy and by CHN-analysis. © 1979 Springer-Verlag.
