Abstract
The performance of liquid-membrane electrodes using A new, synthetic, and electrically neutral ligand in A membrane solvent incorporated in A PVC-matrix is described. In this sensor system, two different membrane solvents are compared in respect to selectivity, pH-dependence, lifetime, working range and dynamic response. Both electrodes show A linear response to sodium ion activities in the range of 10−1M to about 10−5M in unbuffered systems, with A selectivity over potassium, calcium and magnesium which permits measurements in blood serum.Keywords
