| Abstract: | Saccharin can be determined in palladium, gold and nickel electroplating baths by differential pulse polarography or second-harmonic a.c. polarography after extraction with an ethyl acetate/carbon tetrachloride mixture and after masking the noble metal with cyanide. Detection limits lie between 0.025 and 0.005 g l-1. Bath components such as chloride, nitrate, sulfate, phosphate, glucose, citrate, Fe3+, Sn4+, Cr3+, Ni2+ and Pb2+ do not interfere. |
