    Abstract

    Anion selectivities of membranes based on uranyl salophen derivatives with substituents at the 4-position are presented. Derivative 2 (with 4-nitro substituent) has been applied to design a nitrite-selective ion-selective electrode (ISE) that shows linear response in the range 1–3 of pNO2− with a slope of 56.2 mV decade−1. The highest selectivity over other anions and optimum performance of the electrodes are obtained for membranes containing tridodecylmethylammonium chloride (TDMAC) at 10 mol% versus ionophore as an additive.
