Abstract
Na2-xCuxV12O30 (0 < x less than or equal to 1) and Na2-xFexV12O30 (0 < x le ss than or equal to 0.8) P-bronzes were synthesized, and their electrode po tentials were measured as a function of copper and iron concentrations in s olution, The effects of the H+, Na+, K+, Cu+, Zn2+, Fe2+, Co2+, Al3+, and N i2+ ions were assessed, and the corresponding selectivity coefficients were determined. The electrodes were found to be applicable as indicator electr odes in potentiometric determination of the Cu2+ and Fe3+ ions in acid solu tions.
