A lithium-selective glass electrode

We pioneered the study of the electrode properties of glasses containing 80 and 85 wt % LiF and 20 and 15 wt % Al(PO3)(3). LiF-80-based glass electrod es functioned as lithium-selective electrodes in 1-0.0001 M LiCl solutions. Contrary to aliminosilicate glasses, these glasses responded to the Li+ io n better than to the Na+ ion and were nonselective to the H+ ion. This made them promising for the development of sensors for Li+ ions in different so lutions. Forward and reverse transitions of these glasses from the hydrogen to the lithium function and from the lithium to the sodium function are de scribed by the equation of the simple Nikol'skii theory.
