- Abstract
Cross-sensitive DP-sensors based on perfluorinated sulfonated cation-exchange membranes containing hydrated ZrO nanoparticles are used for the simultaneous determination of NovH, LidH, and K ions in aqueous solutions. A significant increase in the sensitivity of DP-sensors to NovH and LidH in solutions of NovHCl + LidHCl, NovHCl + KCl, and LidHCl + KCl compared to sensitivity to HO ions interfering with the determination of corresponding organic cations is achieved by varying the concentration of ZrO in the membranes.
