The successive determination of chloride, fluoride and sodium in single samples of orthophosphate minerals by means of ion-sensitive electrodes.
A buffer system composed of perchloric acid, citric acid and triethanolamine has been used for the successive determination of chloride, fluoride and sodium in a single sample of an orthophosphate mineral. The conventional sodium-sensitive glass electrode compares favourably with the more expensive Orion sodium-sensitive electrode.
