| Abstract: | The contents of Pb and Cd in sulphanilic acid was determinated by DPSA with a thin film of mercury on a silver eletrode, and the contents of Hg slid As with a thin film of gold film on a glassy carbon electrode. The precision and accuracy had been studied. The results showed that this method was simple, high speed, sensitive and reliable. |
