The hydrogen function of the electrodes manifests itself in the pH range 2–5, with a slope of 55, 54, and 54 ± 2 mV/pH for MxV2O5 - nH2O with M = Li, Na, and K, respectively. Their sensitivity range is 10–4 to 10–1 mol/l. The electrode potential as a function of concentration follows the Nernst equation with a slope of 55, 55, and 57 ± 2 mV/pC for M = Li, Na, and K, respectively. The Li+, Na+, K+, Mg2+, Ca2+, Sr2+, and Ba2+ selectivity coefficients of the electrodes are determined Доп.точки доступа: Bakhteeva, Yu. A.
