| Abstract: | The results of tests in fluoride-containing solutions were presented for an antimony electrode, solidstate polyvinyl chloride-graphite electrodes modified by a quinone-hydroquinone series system, and electrodes made of silicate glasses, in particular, of commercial formulations. A technique and criteria were proposed for comparison of the performance characteristics of different glass electrodes in fluoride-containing solutions, and samples most resistant to hydrofluoric acid were identified. |
