| Abstract: | The frequency of a piezoelectric quartz crystal is decreased when iodide is electrodeposited on the silver electrode of the crystal at—0.05 V vs. Ag/AgCl. From 3 × lO-7 M to 1 × 10-5 M iodide can be determined with few interferences, and a procedure for removal of interfering species is given. Iodide is removed from the electrode by electrolysis at —0.4 V after each determination. |
