Abstract: A new method of oscillographic chronopotentiometry at silver disk electrode for the determination was initially investigated and established. By using it, we determined a series of ions. The detection limits were decreased two or three orders of magnitude of that for the oscillographic chronopotentiometry at mercury electrode. This method was characterized by fine sensitivity, stable oscillogram and was not used for mercury. The research on mechanism of this method showed that these achievements were caused by the characteristics of silver electrooxidation and electroreduction and the A.C. oscillographic chronopotentiometry(ACOC).

Key words: Silver disk electrode, Oscillographic determination, Oscillographic chronopotentiometry
