N2 - Anion-selective electrodes with polymer membranes based on manganese(III) tetraphenylporphyrin (TPP) complexes with various axial ligands (chloride, perchlorate, nitrate, and rhodanide) were studied. The electrodes showed high (compared with other anions) selectivity toward the salicylate anion in a wide range of concentrations at different pH values. The selectivity coefficients of membrane electrodes KSal-/Xn-sel were determined by the bi-ionic potential method. A selectivity series was obtained based on K Sal-/Xn-sel, which differs from Hofmeister series for classical anion exchangers. The possibility of using these electrodes in clinical practice for determining salicylate ions in human blood was shown.
